Chapter 2: Printer Status and Indicators
The A776/B780 printer performs a number of diagnostics that provide useful information about the operating status of
the printer. The following diagnostic tests are available.
• Startup diagnostics, performed during startup cycle.
• Runtime diagnostics, performed during normal printer operation.
• Remote diagnostics, run during normal operation and reported in the print test.
The printer can be configured with the following settings and functions through the configuration menu that is printed
on the receipt. To learn more see the section called “Configuring the Printer” in the A776/B780 User Guide, page 26.

Startup Diagnostics
When the printer receives power or performs a hardware reset, it automatically performs the startup diagnostics (also
known as level 0 diagnostics) during the startup cycle. The following diagnostics are performed:
• Turn off motors and solenoids
• Perform boot CRC check of the firmware ROM, test external SRAM, test EEPROM, and test main program CRC
Failure causes Startup Diagnostics to stop; the printer beeps and the light flashes a set number of times,
indicating the nature of the failure. The table in the “Indicators” section (page 16) describes the specific tone and
light sequences.
• Check if paper is present
• Return the knife to the home position
Failure causes a fault condition. The table in the “Indicators” section (page 16) describes the specific tone and light
sequences.
• Check if receipt cover is closed
Failure does not interrupt the startup cycle.
When the startup diagnostics are complete, the printer makes a two-tone beep (low then high frequency), the paper
feed button is enabled, and the printer is ready for normal operation.
If the printer has not been turned on before, or a new EEPROM has been installed, the default values for the printer
functions will be loaded into the EEPROM during startup diagnostics.

Chapter 2: Printer Status, Ethernet and Indicators
Runtime diagnostics
Runtime diagnostics (sometimes called level 2 diagnostics) run during normal printer operation. When the following
conditions occur, the printer automatically turns off the appropriate motors and disables printing to prevent damage
to the printer:
• Paper out
• Receipt cover open
• Printhead too hot
• Voltages out of range
• Knife unable to home
The light on the operator panel will signal when these conditions occur as well as indicate what state or mode the
printer is in.
Remote diagnostics
Remote diagnostics (sometimes called level 3 diagnostics) keeps track of the following tallies and prints them on the
receipt during the print test. These tallies can be used to determine the printer’s state of health.
• Model number
• Serial number

Chapter 3: Migrating to A776 and B780
Migrating from existing CognitiveTPG printers
The A776 printer is the fourth generation two station hybrid thermal/impact printer with feature enhancements
designed to provide the most desirable options to the customer. This section is provided for those customers who
would like to migrate from their existing A760 CognitiveTPG printers to the A776 printer, while maintaining as much
continuity as possible in the new application. Several commands exist to support such a migration. The primary
differences are described below:
A760 to A776:
A760: wide slip station (66 columns) A776: narrow (42 columns) slip station
A760: no top validation of forms
A776: top validation of forms

Moving from the A760 to the A776 (Slip differences)
The impact station print zone on the A760 is 4.7 inches wide and the print zone on the A776 is 3.0 inches. To compensate for
the narrower print zone on the A776 the firmware will provide the following functionality:
1.
For applications that currently use narrow forms with 42 or fewer columns, an option is provided to delete x leading
spaces. No application or form changes should be required.
2.
For applications that use narrow forms with 51 or fewer columns, an option is provided to default to compressed
mode. No application or form changes should be required.
3.
For applications using wide forms that print on less than 51 columns, options 1 and 2 above are combined with the
option to delete trailing spaces. There should be no changes required to the application but a new form will be
required.
4.
For applications using wide forms that print on more than 51 columns, the data will wrap to the next line.
don’t want data to wrap you will need to change the application and the form.

Some commands have new functions for the slip and can be configured to be enabled or disabled on the slip. Existing
applications that use these functions on the receipt but not on the slip may need to be disabled manually for the slip. The
default is disabled for the slip.

The A760 mechanism has a positive slip stop for positioning a form at its top right corner. Some applications rely on a form inserted to this slip stop in order to print on specific areas of the form. When the top
right corner of the form is positioned at the slip stop, the first print line is 0.7” below the top of form. Some
applications rely on the operator manually positioning a form in order to print on specific areas of the form.
The A760 firmware does not automatically reposition an inserted form.
The A776 slip stop override option does not reposition an inserted form.
The A776 slip stop distance option is triggered at the slip selection command (0x1B 0x63 0x30 0x04) and
positions an inserted form prior to print so that the first line of print will match an A760.
There is a temporary run time command to override this configuration option:

Overview of Printing Characteristics
Commands control all operations and functions of the printer. This includes selecting the size and placement of
characters and graphics on the receipt or the slip and feeding and cutting the paper. The programming commands
have been organized, in order of hexadecimal code within functional groups. For this reason, “related” commands may
not be listed adjacent to one another.
The A776 (B780) standard command set allows it to work with software written for CognitiveTPG or other POS
compliant printers.
Any of the commands may be used in any combination to program a host computer to communicate with the printer
(unless otherwise noted).
For the printer to operate properly within an Ethernet environment, a specific set of commands must be set.
Some commands listed and described here may not be implemented and are identified as “not implemented.”
If received, they are ignored and not sent to the print buffer as data.
Any non-legal commands have their parameter sent to the print buffer as data.

set/cancel rotated print (clockwise), and rotated print (counterclockwise).
Rotated clockwise and rotated counterclockwise print commands are mutually exclusive: the setting of the last received
command is effective. Unintended consequences may result when rotated clockwise is mixed with other commands.

The samples of the print show only the normal-size characters. Double-wide and double-high characters are printed in
the same orientation. They may also be mixed on the same line.
Note: The following print modes cannot be mixed on the same line:
• Standard and compressed pitch
• Vertical (normal) and rotated
• Right-side up and upside-down
• Single-high (normal) and double-high

Tenths of seconds
The time that the printer waits for a slip to be inserted is set using the configuration menu. The default is forever, but it
can be set to 1, 3, or 5 minutes.
The value “n” sets the time (n x 0.1 seconds) that the printer waits to close the platen and start printing after the slip has
been inserted. The printer reads that a slip is inserted when the leading edge and trailing edge sensors are covered.
The slip-in light is lit (green) when both sensors are covered.
If a slip is not inserted in the time specified, the receipt station is selected for the next function.

Description
When the monochrome paper type command (00) is set, this command is recognized and retained but has no effect.
The monochrome paper selection (usually black) controls the output.
When two-color paper is loaded and the two-color paper type command set, this command will designate which of
the two colors will be used for everything not specified as having (an) explicit color parameter(s) such as color logos,
side bars, surround graphics, background watermarks or color raster graphics.

Value of m:
0 = monochrome (black) paper

5 = two-color (red/black or green/black) papers
Default: 0 (monochrome paper)
This command will set the optimum parameter values in the thermal print engine control hardware for any defined
monochrome or two-color paper chemistry. The m n parameters select paper category and formulation version,
respectively.
(m n = 0 0) defines the default monochrome (black category, initial version) paper, out-of-box printers will also have
factory pre-set descriptions for customer selected color types; initial release consists of three defined color types:
(m n = 4 0) blue/black paper, and (m n = 5 0) red/black paper or green/black paper..
When issuing this command a value of n = 0xFF can always be used; that is interpreted as requesting the setting of the
highest version defined in the printer of that category. This is a safe way for an application to always select the latest of
a manufacturer’s paper category, thus choosing “ latest standard red/black”.
An incorrect setting of m n for a two-color paper or non-standard monochrome paper, or failure to set m n when a
color paper is inserted will result in poor print quality printing.
The last set paper type choice is stored in non-volatile memory and is retained after a power loss and across reset
commands. The initial value at first boot after firmware load (or reload) is m n =0 0.

Sets the right side character spacing to [ n x horizontal or vertical motion units]. Values for this command are set
independently in standard and paper mode.
The units of horizontal and vertical motion are specified by the set horizontal and vertical minimum motion units
(1D 50 …) command. Changes in the horizontal or vertical units do not affect the current right side character spacing.
When the horizontal or vertical motion unit is changed by the set horizontal and vertical minimum motion units
(1D 50 …) command the value must be in even units and not less than the minimum amount of horizontal movement.
In standard mode the horizontal motion unit is used.
In page mode the horizontal or vertical motion unit differs and depends on the starting position of the printable area.
When the starting printing position is the upper left or lower right of the printable area (set by select print direction
in page mode, 1B 54 n) the horizontal motion unit (x) is used. When the starting printing position is the upper right or
lower left of the printable area (set by select print direction in page mode, 1B 54 n) the vertical motion unit (y) is used.
The command can be enabled or disabled for the slip. Default is disabled for the slip on A776, and enabled on B780.

This command is effective for all characters (except for HRI characters).
In standard mode, the vertical direction is the paper feed direction, and the horizontal direction is perpendicular to
the paper feed direction. However, when character orientation changes in 90 degree clockwise-rotation mode, the
relationship between vertical and horizontal directions is reversed.
In page mode, vertical and horizontal directions are based on the character orientation. When characters are enlarged
with different sizes on one line, all the characters on the line are aligned at the baseline.
The select print mode (1B 21 n) command can also select or cancel double-width and double-height modes. However,
the setting of the last received command is effective.

Turns on white/black reverse print mode. In white/black reverse print mode, print dots and non-print dots are reversed,
which means that white characters are printed on a black background. When the white/black reverse print mode is
selected it is also applied to character spacing which is set by right-side character spacing (1B 20).
This command can be used with built-in characters and user-defined characters, but does not affect the space
between lines.
White/black reverse print mode does not affect bit image, downloaded bit image, bar code, HRI characters, and
spacing skipped by horizontal tab (09), set absolute starting position (1B 24 …), and set relative print position (1B 5C).
White/black reverse print mode has a higher priority than underline mode. When underline mode is on and white/

Sets a mode for reverse printing effects on text. The background color is specified by m, while the text color is specified
by n. Setting m = 0 turns off the mode.
If m = n but not zero, the printer produces solid printing in the given color. This tactic can be used to minimize the
firmware busy work.

Default:
n = 0 (off )
Prints a strike-through over characters. If the strike-through is as wide as the cell height, this will produce a cell that will
be printed as a solid current color.
When characters are greater than normal size, such as double-high, the number of character rows claimed by n also
increases proportionally, such as doubling for double-high cells. Location of the strike-through on a cell is on a cell-bycell basis, so mixing cell sizes on the same print row will give uneven results.

See also command “Expanded flash memory allocation” (1D 22 80...) and “Select flash area” (1D 22 81 n).
Important: While erasing flash memory, the printer disables all interrupts, including communications. To provide feedback
to the application, the printer responds to the application when the erase is complete with a 0D (Hex). After sending the
erase user flash sector (1D 40 n) command, an application should wait for the response from the printer before sending

Enters a downloaded BMP logo into RAM or flash.
The downloaded BMP logo can be printed by using the print downloaded bit image (1D 2F m) command.
To downloaded BMP file to save it as a logo, send the hexadecimal code 1B followed by the whole BMP file.
The printer decodes the BMP file header and will save the image data after checking important parameters, such as
width, height, and the number of colors (only monochrome images are accepted).
BMPs and bit images are definable for the receipt station. However, there is no longer an automatic erasure whenever
the user downloads a character set (as happened previously) as well as in the case where the current logo was never
set > 0, (the automatic erasure if user flash memory had filled up with inactive logo 0 definitions upon next power
cycle). Warnings about the effect of running out of defined logo space during a download apply (i.e. the command is
ignored). The application is required to manage user data space, downloaded font space, and logo space.
After downloading a logo to the printer, wait 100 ms to allow the printer time to write the logo to flash.
The downloaded BMP file can be printed by using the print downloaded bit image (1D 2F m) command.

Range of n:

Default: 0
Selects a color or monochrome logo to be defined or printed. The active logo n remains in use until this command is
sent again with a different logo n.
When this command precedes a logo definition, that definition is stored in flash memory as logo n. If there is already
a different definition in flash memory for logo n, the first is inactivated and the new definition is used. The inactive
definition is not erased from flash and continues to take up space in flash memory.
When this command precedes a logo print command and n is different from the previously active logo selected, the
printer retrieves the logo definition for n from flash memory and prints it. If there is no definition for logo n, then no
logo is printed.
In the case of a previously existing application that expects only one possible logo, the printer will not receive the
select current logo (1D 23 n) command. In this case, the printer assigns 0 as the active logo identifier. It automatically
stores any new logo definition in flash memory as logo 0, inactivating any previous logo 0 definition. If the flash
memory space available for logos fills up with inactive logo 0 definitions, the firmware erases the old definitions at the
next power cycle. This is the only case in which the printer erases flash memory without an application command.
In the case of a new application using multiple logos, the select current logo (1D 23 n) command is used. After that, the
printer no longer automatically erases the logo definition flash memory page when it fills with multiple definitions. A
new application using multiple logos, writing a user-defined character set into flash memory, or both, is responsible
for erasing the logo and user-defined character set flash memory page when the logo area is full or before a new
character set is defined.

This command is only valid for the receipt station, However, it will be processed correctly, regardless of whether the

Value and range of n: n1 to n72/n80 corresponds to one dot row data for a thermal receipt printer.
Each bit defines whether or not a dot of the current color will be printed. This command is used for printing a
monochrome graphic in real-time. Offsets, page and any other modes or overlays, including watermark do not apply
and are overridden by this command. A complete rendering of the intended final image should have been done by the
application before sending the dot rows.
If two-color paper is indicated by the set paper type command, then the raster will be printed in the color that is
defined by the set current color command.

29 13 n1…..n144 (576 dots 80 mm paper) / n160 (640 dots, 82.5 mm paper)
Value and range of n: n1 to n144 / n160 corresponds to one dot row data.
For each printed dot row starting at the top left, two-part bit strings are used to define (in the first half ), all dots that
are of either color (i.e. not white). The second half string defines only the dots where the color = black. Thus all dots
which are on in the first half string but not on in the second half string, select the secondary color. The parameter of
this command is thus a string of bytes for one dot row with the same structure as defined for the thermal color format
file given in the download color
logo command.
This command is used for printing a single raster of color graphics in real-time. Offsets, page and any other modes or
overlays, including watermark, and current color do not apply to this command. A complete rendering of the intended

The latest value from the set current logo command will be the logo index to be used to store the downloaded
graphic.
m identifies whether the image is monochrome (which requires one parameter bit row description) or two-color,
which requires a pairing of bit descriptions for each row.
n1 * n2 define a rectangular image n1 bytes wide and n2 bytes long. n1*8 specifies the number of dot columns, and
n2*8 the number of dot rows. That is, each row is defined by an integral number of bytes and the number of rows is
also an integral number of bytes. Note that n2 can be any length, subject to memory space availability.
For each color dot row starting at the top left, a two part parameter byte string is used to define first, all dots that are
not white, and the second half defines all dots where the color = black. Thus all dots that are on (=1) in the first half but
not on in the second half select the paper-color. A sequence of these raster row strings is used to specify the complete
logo. In the monochrome case, only one bit is needed per row. This is the same structure as used for the definitions of
print raster monochrome graphics and print raster color graphics.
This command is used for storing a logo of n1 by n2 size indexed by the current logo value.
After downloading a logo to the printer, wait 100 ms to allow the printer time to write the logo to flash.
Monochrome shade mode (ColorPOS®)
ASCII
Hexadecimal
Decimal
GS 0x86 m
1D 86 m
29 134 m
This applies a selected shade density to all monochrome objects such as text and monochrome logos. The parameter
m specifies the shading effect and has an initial value of 0 which signifies no effect.
m specifies the percentage of shading, 0 <= m <= 100.
m = 0 is the initial value and turns this mode off.
Note: Only a few gradations will be perceptible, so large increments of m, such as 20, should be used. If a reverse print mode
is on, the shade effect will be applied to the background only.
When the current color mode is set to black, increasing values of m relate to the relative amount of (white) paper that
replaces black dots. Analogously, when the paper-color is the current color, m defines the relative amount of color dots
being “erased” by white originals of the paper.
Both text and monochrome graphics are affected by this command.
Turning monochrome shade mode on, turns color shade mode off.

29 135 m
This applies a mixing of color into any monochrome objects such as text and monochrome logos. Rather than fading
away, this mode transitions a character or logo from the current color in which it would normally be printed to the
other color. The parameter m specifies the shading effect and has an initial value of 0 which signifies no effect. m
specifies the percentage of shading, 0 <= m <= 100.
m specifies the percentage of shading, 0 <= m <= 100.
m = 0 is the initial value and turns this mode off.
Note: Only a few gradations will be perceptible, so large increments of m, such as 20, should be used. If a reverse print mode
is on, the shade effect will be applied to the background only.
When the current color mode is set to black, increasing values of m relate to the relative amount of paper-color that
replaces black dots. Analogously, when the paper-color is the current color, m defines the relative amount of black
color dots replacing the paper-color ones.
Both text and monochrome graphics are affected by this command.

This command will print logo n. The command is ignored if a logo with index n has not been defined. If m = 0 the
color(s) as defined in the logo is (are) used; if m = 1 and if the logo is a color one, then the two color planes (black and
paper-color) in the logo are swapped.
Apply shading to logo (ColorPOS®)
ASCII
Hexadecimal

GS 0x8B n m o
1D 8B n m o
29 139 n m o
This command will apply shading effect m to logo n and store it at index o, also extending width to full horizontal size
if logo n is not at full paper width.
n must be the index value of an existing logo
0 <= m <= 100, possibly resulting in a logo suitable for background watermark mode use
o can be any value, and the logo will be placed according to the current setting of user storage into RAM or flash
memory.
An application might use a high value of m to shade out the logo if the original image has a significant number of “on”
dots to allow for future foreground print readability.
Note: The old logo size and current justification mode are used to create a new logo image at full paper width size by filling
in white space at either or both sides if needed. This new logo will provide for minimal performance impacts when it is
selected for use in watermark mode.
After sending the shading command, wait 5 seconds to allow the printer to apply the shading and write the results to
flash.

Merge watermark mode (ColorPOS®)

GS 0x8C n m

Default
0 (off )
This command will insert the logo m as a repeated background image, similar to printing a visible watermark, into the
print stream. The space between repetitions of this usually shaded logo will be every n*8 dot rows.
n >0 = number of dot rows x8 to skip before repeating the merge action
m specifies the index value of the logo. If no logo has been defined with this index then the command is ignored.
Note: Horizontal placement of a watermark logo was fixed at the time the logo was Shaded or when it was downloaded as
a full width logo for watermark use. This command will be ignored if the current logo is not at full paper width size (see the
apply shading to logo command for preparing logos for watermark use).
The merge process is performed after all other image formation and takes whatever print raster data is ready to be
put on paper. It “adds” (computer logic OR) the mono or color bits to the print row. Generally, if the print dot was to be
white or same color as the watermark dot, the print dot will be the color of the watermark; otherwise it will be black.
Form and merge real-time surround graphic (ColorPOS®)
ASCII
GS 0x90 m x y o p q
Hexadecimal 1D 90 m x y o p q
Decimal
29 144 m x y o p q
This command will print a real-time graphic style designated by m. m = 0 rectangle, m =1 oval, m =2 ellipse (if printed
in a square area the ellipse becomes a circle),
m = 3 is a 5 point star, m = 4 is a free hand underline,
m = 5 is a free hand ellipse and other values of m reserved for future styles. This graphic is formed into a RAM based
graphics buffer, and the buffer state is set to “graphic merge pending”.
Whenever the buffer is in the pending merge state and print output is started, the state will be changed to frozen and
a merge process started (logically OR-ed graphic data) into the print lines that follow. The application determines how
close the graphic is to any printed character data by subsequent printing of blank lines or blank dot rows. The merge
process stops when the buffer is exhausted or its state changed (by a save graphics buffer as logo or new form and
merge real time surround graphics command). The form and merge real time surround graphics command can be
given multiple consecutive times, allowing the application to set up a multi-polygon background before starting its
printout with placed text or logo.
The geometric location points for this graphic are defined by a rectangular area start position of x bytes from the left
edge and y bytes from the top of the new line and times
o bytes wide times p bytes in length. For the case of
m =3 (star), the value passed for o is also used as the implicit p value (passed value is ignored), i.e. a square area. The
thickness of the graphic is defined by q dots. This will form a bit image in a RAM graphics buffer. Subsequent surround
graphic commands can be added into (logical OR process) with expanded size if needed) the graphics buffer until an
output action is issued. It is expected that area left white will then be (usually) filled in with text or other data that is to
be printed. Printing starts as soon as the first line of data or other printout arrives. After this printing is started, any new
surround graphics commands will set the graphics buffer to a merge pending state. Example: Create different size stars
and an ellipse around a block of text.
The graphics buffer is at a frozen state at printer initialization or reset, with blank data in it.
Each the time this command is given, the current color and shade mode values (if any) are used for the surround
graphic, and may be changed before any subsequent surround graphics and/or printing output. This command may
be used in page mode.

GS 0x99 l m n o
1D 99 l m n o
29 153 l m n o
Value of l:
l is a binary switch:
0 = disables margin message merging
1 = enable left margin message merging
2 = enable right margin message merging
l > 2 ignore command
Value of m:
m is the ID (index) of the logo to be used in the merging. If a logo with index m does not exist or is wider
than the print raster width then this command is ignored.
Value of n:
merge
n is the number of raster rows to be empty (skipped) before repeating the designated margin message
Value of o:
o is a right – left toggle switch:
o = 0 no toggling of the margin message merge
o = 1 enable toggling, starting with a left margin message first
o = 2 enable toggling, starting with a right margin message first
o > 2 ignore entire command
This command performs a dynamic merge of a designated logo/message (or logo/message pair, which can be the
same) into each raster line to be printed after the character data has been placed and in conjunction with any other
active merge modes. The parameter l specifies whether merging should take place from the left side or the right side.
A left side merge followed by a right side merge (or vice-versa) must be issued, with the latter side merge command
setting the toggle switch = 1 or 2 will create the desired left – right printing effect. Each merge side retains its n value
of raster rows to be skipped. If toggling is not selected when both sides are defined, then if the n skip row values are
different, or the logo height sizes are different, the side logos will not line up as printing progresses. If toggling is
selected then both left and right sides merge margin message must be defined; otherwise toggling is ignored.
Each side logo can be > ½ of the raster print line. In that case the printing process is additive in the overlap region. This
command with the first parameter l = 0 turns all margin message merging to off.
Shade and store logo (ColorPOS®)

GS 0x9A n m o
1D 9A n m o
29 154 n m o
Value of n:
n is ID (logo index value) of an existing logo in either flash or RAM memory
Value of m:
m is the % of shading to be applied to the logo, 0 <= m <=100.
Value of o:
o is the new ID (logo index value) to be used to store the shaded result, according to the current setting of
user storage into flash or RAM.
This command applies shading to an existing logo of any size, storing the result in a new logo at index o. The new logo
is thus better suited for use in a merging mode. The % of shading will have only a few perceptible gradations, so large
increments (20 is suggested) should be used to achieve visibly distinct effects.

#dot rows = n x 24, n = 5 is the recommended setting
Because the printhead and cutting knife are physically separated, it is necessary to advance the printed area of a
receipt past the knife to avoid the last of the printing from being cut off. This advance of paper however, causes a blank
space at the start of the next receipt that could be used. To utilize this space and reduce paper usage, this command
starts to print a logo for the next receipt before initiating the cut at the end of the current receipt. At a set location
during the printing of the logo, the corresponding paper advance is stopped and a paper cut performed.
The formula “n x 24” is used to determine the number of dot rows to move the paper from the start of the logo to the
position of the cut.
If n x 24 is greater than the height of the logo, the logo height is used to determine the cut position. If n = 0 the cut is
eliminated.
In order for this command to function properly, all commands used by legacy applications to move the end of the
current receipt past the knife should be removed.

0
This command configures into EEPROM (permanent configuration switch setting) a set of features that allows
placement of a color logo in the header, full-time margin message printing, watermarking in the middle of the receipt
and printing of a trailer color logo. These commands are triggered by any knife cut command (partial or full: 19, 1A, 1B
69, 1B 6D, 1D 56 m n). The printer when powered-up will (if set) activate the header, watermark, and margin message
features and will be ready to print the body of a receipt. For selected features to print however, logos with defined
index values of F0, F1, F2, F3 respectively must be saved in the flash memory.
Once logos have been loaded and enabled they can be used in any emulation mode. Skip distances remain constant.
Value descriptions:
f = function selector and defines which parameters
are used :
s = dot row space before object distance
p = dot row past an object
r = repetition space distance in mm
t = margin message toggle mode
f = 0 turn off all LogoEZ® colorization functions (default). No other parameters are required.
f = 1 link print logo after knife cut – equivalent to printing a transaction header graphic.
Example:
Print logo (#F0) after a knife-cut with “s” dot row spacing before the logo and “a” dot row spacing after the logo (1F 03
16 01 s p). After executing a knife-cut command, if s > 0, execute the following:
•
Stop background merging (1D 9B 1 command)
•
Skip s (feed paper) dot rows (15 s command) – adds spacing in addition to any set by the application around a
knife cut command
•
Set centered justification (1B 61 1 command), saving the previous justification
•
If the logo at F0h is currently defined, print logo by sending print downloaded bit image, normal size (1D 2F 0
command) without changing the value of current logo
•
Reset justification to previous value (1B 61 [previous value])
•
Skip (feed paper) “p” dot rows after logo (15 p command)
Since the normal space on the receipt paper after a knife cut is 18 mm (144 rows), no extra space is usually needed
above the logo. The default value is s = 0 and turns off the f = 1 logo after knife-cut link.
f = 2 link watermark printing
Example:
Activate watermark printing using logo #F1 (1F 03 16 02 s r) with “s” being the skip distance in dot rows before
activation and “r” is the distance in mm between watermark repetitions.

After executing a knife-cut command and the f = 1 steps, if s > 0, execute the following:
•
Skip “s” (feed paper) dot rows (15 s command)
•
Set watermark printing to “on” using logo F1 (execute merge watermark mode -1D 8C r F1 command). Logo
must be defined for F1 and comply with watermark mode requirements in order for this happen.
•
Stop background merging mode (1D 9B 1 command). Clears background for logos, barcodes, and captured
images.
The watermarks feature is now activated (following an optional F0 logo) to start after each knife cut. Note that when
printing graphic objects, merging is turned off by each knife cut. The default value is s = 0 and turns off the f = 2
watermark link.
No correlation exists (when both are set) between watermark and logo skip distances.
If the f = 4 logo link is undefined, you should set a null trailer logo with s = 1 and p = 144 (1F 03 16 04 1 90, no logo
at index F3). This will turn off watermarks at the position of a knife cut and leave a clear space at the top of the next
receipt.
f = 3 link margin message printing
Example:
Activate margin message printing using logo #F2 (1F 03 16 03 s r t) with “s” being the skip distance, “r” the distance
between repetitions and “t” the toggle mode.
Toggle mode values for t:
0 = both left and right side
1 = toggle sides, starting with left side
2 = right side margin message only
3 = left margin message only
After executing a knife cut command and the f=1 steps, if s > 0, execute the following:
• skip “s” dot rows (=15 s command). When both watermark and margin message merging are defined, the
respective “s” values are treated independently. The same value should be used to start watermark and
margin message at the same place.
• Use the toggle mode values listed above to apply margin message for the left and/or right side. For a margin
message on both sides, enter the 1D 99 1 F2 p 0 command followed by the 1D 99 t’ F2 r t’ (apply margin
message) command with the logo at index F2 defined.
• suspend background merging mode (=1D 9B 1 command), so any logos, barcodes, and captured images will
print in the clear
The margin message printing feature is activated after the header logo after a restart at each knife-cut. Note that when
printing graphic objects, merging is turned off by each knife cut. No correlation exists (when both are set) between
watermark and logo skip distances.

If the f = 4 logo link is undefined, you should set a null trailer logo with s = 1 and p = 144 (1F 03 16 04 1 90, no logo at
index F3). This will turn off margin message at the position of a knife cut and leave a clear space at the top of the next
receipt.
f = 4 link logo print before cut
Prints a logo after the skip distance of “s” before a logo and “p” past a logo and performs a knife cut (1F 03 16 04 s p).
Immediately before executing a knife-cut command, if s > 0, execute the following:
• skip (feed paper) “s” dot rows (15 s command)
• stop background merging (1D 9B 1 command). Save previous background merging value, so logo prints in
the clear
• set centered justification (1B 61 1 command), saving the previous justification • if a logo at index F3h is currently defined, print the logo by sending print downloaded bit image, normal size
(1D 2F 0 command), without changing the value of current logo.
• reset justification to previous value (1B 61 [previous value])
• skip (feed paper) “p” dot rows (15 p command) a minimum value of 90h, to ensure knife cut occurs after the
logo
• restore background merge suspension (1D 9B [previous value])

This command configures into EEPROM (permanent configuration switch setting) one or two combinations of
character attribute mappings, including substitute attribute settings for color effects. The attributes of the character
code are used to form the desired pixel character when the code is placed into the raster print buffer. An “m” bit value
set to on in the “original attribute mapped table” above will have its attributes set to the corresponding bit value of “s”
in the “attributes substituted table”. If m = 0 then no substitution takes place.
The command is available only in A776 native mode. Once attributes have been defined and enabled they can be
used in any emulation mode. A776 native mode must be used to turn the feature off.

The operational theory of this command is that if (input character attributes) AND (original) = (original); then (output
character attributes) = ([original] X OR [input character attributes]) OR (substituted). The input character’s original
attributes are mapped to the substituted attributes, but any attributes not specified for mapping are unchanged.
In the tables you will see that there are 7 input attributes and 9 outputs. It is expected that the alternate color attribute
will be used most. For example, when the alternate color attribute is combined with the reverse substitution attribute,
the result is white characters on a color background. The color reverse attribute without alternate color will print black
text on a color background. Any mappings utilizing compressed and/or double-wide attributes will effect the length
of a line and could cause unintended line wraps. Mappings containing double-high attributes could cause unintended
receipt lengths.
When both attribute mappings are set, processing is perform in order sequence. When two text attribute substitutions
contain conflicting dependent remappings, the result is undefined.

Chapter 5: Programming commands
Status
Status command introduction
The A776 has three methods of providing status to the application. These methods are through batch status
commands, real time status commands and unsolicited status mode. An application may use one or more of these
methods to understand the current status of the printer. A brief description of each of these methods follows.
Batch status commands – These commands are sent to the printer and stored in the printer’s buffer. Once the printer
has processed all the previous commands these commands are processed and the proper status is returned to the
application. In the event a condition causes the printer to go BUSY, it stops processing commands from the printer
buffer. If a batch status command remained in the buffer during this busy condition, it would not be processed. In fact,
no batch commands are processed while the printer is in this state.
Real-time commands – These commands are sent to the printer and stored in the printer buffer. Periodically,
when the printer has time, it scans the input buffer looking for these commands. When found by the printer, these
commands are processed immediately. This gives the application the ability to query the printer when it is in a busy
state in order to correct whatever fault has occurred.
Unsolicited status mode – This mechanism allows the application developer to program the printer to automatically
respond with a four byte status when certain conditions in the printer change.
Please see the subsequent sections for a more detailed description of these status commands. At the end of this
status commands section is a page entitled “Recognizing data from the printer”. This describes how to interpret what
command or setting (in the case of unsolicited status mode) triggered a response from the printer.
Batch mode
For RS-232C printers, these commands enable the printer to communicate with the host computer following the
selected handshaking protocol, either DTR/DSR or XON/XOFF. They are stored in the printer’s data buffer as they are
received, and are handled by the firmware in the order in which they are received.
When a fault occurs, the printer will go busy at the RS-232C interface and not respond to any of the batch mode printer
status commands. If the fault causing the busy condition can be cleared, such as by loading paper, or letting the
thermal printhead cool down, the printer will resume processing the data in its receive buffer.

Range of n:

Transmits the status specified by n. This is a batch mode command which transmits the response after all prior data
in the receive buffer has been processed. There may be a time lag between the printer receiving this command and
transmitting the response, depending on the receive buffer status.
When DTR/DSR RS-232C communications handshaking control is selected, the printer transmits the one byte response
only when the host signal DSR indicates it is ready to receive data.
When XON/XOFF RS-232C communications handshaking control is selected, the printer transmits the one byte
response regardless of the host signal DSR.
When unsolicited status mode (USM) is enabled using the enable/disable unsolicited status mode command (1D 61),
the status transmitted by this command (transmit status) and the USM status must be differentiated according to
the information found in recognizing data from the printer. This is found in the real time commands section of this
document.
The status bytes to be transmitted are described in the following four tables.
Exceptions
When n is out of the specified range, the command is ignored.
The A776 has a single connector that shares data reporting from either cash drawer. When either cash drawer is open,
an open status is reported by the printer.

The printer returns 8 bytes containing the boot and flash software version. The first 4 bytes returned are an ASCII string
for the boot version.
The second 4 bytes are an ASCII string for the flash version. Example: For 1.234.56 (8 bytes), the boot version is 1.23 and
the flash version is 4.56.
Real-time commands
The real time commands provide an application interface to the printer even when the printer is
not handling other commands:
• Real-time status transmission: GS (Hex 1D) sequence and DLE (Hex 10) sequence
• Real-time request to printer: GS (Hex 1D) sequence and DLE (Hex 10) sequence
• Real-time printer status transmission
The batch mode printer status commands are placed in the printer’s data buffer as they are
received and handled by the firmware in the order in which they were received. If the paper exhausts while printing
data that was in the buffer ahead of the status command, the printer goes busy at the RS-232C interface and suspends
processing the data in the buffer until paper is reloaded. This is true for all error conditions: knife home error, thermal
printhead overheat, etc. In addition, there is no way to restart the printer after a paper jam or to cancel a slip waiting
condition when using the wait for slip command.
The real-time commands are implemented in two ways in order to overcome the limitations of batch mode status
commands. Both implementations offer the same functionality; which one you choose depends on the current usage
of your application.
Preferred implementation
For a new application the GS (1D) sequences are recommended to avoid possible misinterpretation of a DLE (0x10)
sequence as a clear printer (0x10 0, ASCII DLE NUL) command.
An application using these GS (1D) sequences, does not need to distinguish for the printer between the new real time
commands and the clear printer command. This implementation is ideal for an existing A756 application that already
uses the clear printer command or for a new application being developed.
Alternate implementation
The alternate implementation uses the DLE (0x10) sequences as implemented on other printers. An application using
these DLE (0x10) sequences and the original A756 clear printer command (0x10) must distinguish for the printer
between the new real time commands and the clear printer command by adding a NUL (0x00) to the clear printer
command.
An application using these DLE (0x10) sequences must also send the second byte of the sequence within 100
milliseconds of the first, to prevent the first byte being mistaken for a clear printer command.
Rules for using real-time commands
Three situations must be understood when using real time commands.
First, the printer executes the real time command within a few msec of detecting it in the input buffer and will transmit
status regardless of the condition of the DSR signal.
Second, the printer transmits status whenever it recognizes a real time status transmission command sequence, even if
that sequence happens to occur naturally within the data of another command, such as graphics data.
In this case the sequence will also be handled correctly as the graphics data it is intended to be when the graphics
command is executed from the buffer.
A776 (B780) Programming Guide
A776-PG00001 D 07/13
Chapter 5: Programming commands
83
Third, care must be taken not to insert a real time command into the data sequence of another command that consists
of two or more bytes.
In this case the printer will use the real time command sequence bytes instead of the other command’s parameter
bytes when finally executing that other command from the buffer; the other command will NOT be executed correctly.
These three situations generally preclude use of standard DOS drivers for the serial communication ports when using
real time commands.
Moving data through the buffer
Applications should not let the buffer fill up with real time commands when the printer is busy at the RS-232C
interface. A busy condition at the RS-232C interface can be determined by bit 3 of the response to 1D 05, or 1D 04 1, or
10 04 1. The reason for a particular busy condition can be determined by other responses to 1D 04 n or 10 04 n.
Although the printer responds to real time commands when it is busy, it will place them into the buffer behind any
other data there, and flush them out in the order in which they were received. When the printer is busy due simply to
buffer full (that is, it can’t print data as fast as it can receive it), then data continues to be processed out of the buffer at
approximately print speed and the real time commands will eventually get flushed out.
When the printer is busy due to an error condition, then data stops being processed to the buffer until the condition
clears one way or another. In either case, but more quickly in the case of an error condition, the buffer can fill with real
time commands.
When the DLE (0×10) sequences are being used, the last byte stored when the buffer fills up could be the DLE (0×10)
code, with no room for the subsequent EOT or ENQ. When this lone DLE (0x10) byte is finally processed out of the
buffer it will be interpreted as a clear printer command.
Similarly, when the GS (1D) sequences are being used, the last byte stored when the buffer fills up could be the GS (1D)
code, with no room for the subsequent EOT or ETX or ENQ. When this lone GS (1D) byte is finally processed out of the
buffer it will use the next byte, whatever it is, as the second byte in its GS (1D) sequence.
To guard against this situation, the application must determine the cause of a busy condition and take appropriate
action or pace the real time commands to avoid filling the buffer. There is a minimum of 256 bytes available in the
printer’s buffer when it goes busy.
Busy line and fault conditions
If the printer is in error condition (cover is open, paper is exhausted…), the printer will still accept data, respond to the
batch mode status commands (1B 76 and 1B 75 0), handle the cash drawer commands, and not go busy until it actually
tries to execute a print command. Then it will stay busy and stop processing data out of the receive buffer until the
condition clears. It will respond to the real time commands as described below.

is handled exactly the same as 10 04 n.

Value of n:
1 = recover and restart
2 = recover and clear buffers
3 = cancel slip wait
The printer responds to a request from the host specified by n. This command includes two sequences: GS and DLE.
The operations performed depend on the value of n, according to the following parameters.
n=1
Restarts printing from the beginning of the line where an error occurred, after recovering from the error. Print
settings that are normally preserved from line to line, such as character height and width, are still preserved with this
command. This sequence is ignored except when the printer is busy due to an error condition.
This command will attempt recovery from a knife error. Other errors associated with the receipt, such as paper out or
printhead overheating, can be recovered from only by clearing the specific condition, such as loading paper or letting
the printhead cool down.
n=2
Recovers from an error after clearing the receive and print buffers. Print settings that are normally preserved from line
to line, such as character height and width, are still preserved with this command. This sequence is ignored except
when the printer is busy due to an error condition.
The same error recovery possibilities exist as for n = 1.
n=3
Cancels the slip waiting status. This sequence is ignored except when the printer is waiting for a slip to be inserted.
When slip waiting is canceled, the receive and print buffers are cleared and the receipt is selected. When printing on
the slip is to continue, the slip must be selected again.
Exceptions
The command is ignored if n is out of range
An application using the DLE sequence must send ENQ within 100 milliseconds of DLE or the printer will misinterpret
the DLE and execute a Clear Printer command. Avoid this possibility by using the 1D 03 n sequence that is handled
exactly the same as 10 05 n.

Enables or disables automatic return of 4 status bytes whenever one or more of the listed changes occurs. This
command is a batch mode command; that is, it is processed after all prior data in the input buffer has been processed.
There may be a time lag between the printer receiving this command and enabling unsolicited status mode (USM),
depending on the pending input buffer contents.
If an immediate return of printer status is desired, then any of the other status commands should be issued following
this command. Once this mode is activated, the printer automatically transmits 4 status bytes whenever any of
the conditions change. If an RS-232C connection with hardware flow control is used, all four status bytes will be
transmitted without checking DSR.
This command is a POS version of general printer unsolicited status functions; it uses the same command code as older
versions of the POS command “automatic status back (ASB)” but has the following differences:
• The parameter n is an on/off switch; it does not select trigger subset.
• There is no immediate return when this mode is turned on.
• All 4 status bytes are always returned.
A change in any of the following conditions will trigger the USM response:
• Cash Drawer
• Receipt Cover
• Knife Error
• Out-of-Range Printhead Temperature
• Out-of-Range Voltage
• Paper Exhaust Status
• Slip Paper
Related information
When Unsolicited Status Mode is enabled using this command, the status transmitted by other commands and the
USM status are differentiated according to the information found in Recognizing Data from the printer, which follows
the USM return description.

Bar codes
These commands format and print bar codes and are described in order of their hexadecimal codes.
Two-dimensional bar code QR code
QR code is a 2-dimensional matrix symbology consisting of an array of nomimally square modules arranged in an overall
square pattern using the QR symbology. A unique pattern at three of the symbol’s four corners assists in determining the
bar code size, position, and rotation.
A series of five commands are required to create and print QR codes.
1. Select the model
1D 28 6B 04 00 31 41 n1 n2
2. Set size of module
1D 28 6B 03 00 31 43 n
3. Select the error correction level 1D 28 6B 03 00 31 45 n
4. Store the symbol data
1D 28 6B qL qH 31 50 30 f1…fk
5. Print the symbol data
1D 28 6B 03 00 31 51 30
The details of each command are described below.
Note: The settings for model, size of module, and error correction level are effective until the printer is reset, or the power
is turned off.

Note:
•
k bytes of f1…fk are processed as symbol data.

This command encodes and prints the QR code symbol data in the symbol storage area, based on the settings in the
previous four commands.
In standard mode, use this function when printer is “at the beginning of a line,” or “there is no data in the print buffer.”
The symbol size that exceeds the print area cannot be printed.
If there is no data in storage, or if the data in the storage area is more than the data allowed by specified model and data compaction mode, the QR code cannot be printed.
The following data are added automatically by the encode processing.
Position Detection Patterns
Separators for Position Detection Patterns
Timing Patterns

Printing of symbol is not affected by print mode (emphasized, double-strike, underline, white/black reverse printing, or
90° clockwise-rotated), except for character size and upside-down print mode.
In standard mode, this command executes paper feeding for the amount needed for printing the symbol, regardless of the
paper feed amount set by the paper feed setting command, The print position returns to the left side of the printable area
after printing the symbol, and printer is in the status “beginning of the line,” or “there is no data in the print buffer.”
In page mode, the printer stores the symbol data in the print buffer without executing actual printing. The printer moves
print position to the next dot of the last data of the symbol.
A quiet zone of four times the size of one module is required on all sides of the QR code symbol, but it is not included in
the printing data. Be sure to add a quiet zone when using this function.

Selects the bar code type and prints a bar code for the ASCII characters entered. If the width of the bar code exceeds
one line, the bar code is not printed.
There are two variations to this command. The first variation uses a NUL character to terminate the string; the second
uses a length byte at the beginning of the string.
The check digit is calculated for UPC and JAN (EAN) codes if it is not sent from the host computer.
Six-character zero-suppressed UPC-E tags are generated from full 11 or 12 characters sent from the host computer
according to standard UPC-E rules. Start/stop characters are added for code 39 if they are not included.
Rotated barcodes set with small modules (select bar code width command 1D 77 n , with n = 1 or 2) and PDF 417
barcodes in any orientation are printed at low speed, for better readability.
Exceptions
The command is only valid at the beginning of a line.
Illegal data cancels the command.
Values:

PDF 417 is a multi-row, continuous, variable length symbology which has high data capacity. Each symbol has
between 3 and 90 rows, with each row containing a start pattern, a left row indicator, 1 to 30 data characters, a right
row indicator and a stop pattern. The number and length of the rows are selectable, which allows the aspect ratio to be
adjusted to particular labeling applications. There are no separator bars between rows.

A776 (B780) Programming Guide

Chapter 5: Programming commands
Each character has four bars and four spaces within 17 modules, and is assigned a value between 0 and 928. For this
symbology, it is common to refer to these character values as “code words.”
There are three mutually exclusive sets of symbol patterns, or clusters, each having 929 distinct patterns. Because
different clusters are used for adjacent rows, it is possible for the decoder to tell if the scanning path is crossing row
boundaries without the use of separator bars.
Sample symbol description:
Each PDF 417 symbol consists of 3 to 90 stacked rows surrounded on all four sides by a quiet
zone. Each row contains:
1 Leading quiet zone
2 Start pattern
3 Left row indicator characters (code words)
4 One to thirty data characters (code words)
5 Right row indicator character (code words)
6 Stop pattern
7 Trailing quiet zone
The number of characters in a row and number of rows can be adjusted to vary the symbol’s overall aspect ratio to best
fit an available space.
Each row has a left and right row indicator with a data region between. The left-most character in the top row of the
data region is the total number of characters in the data region, excluding error correction characters. Characters
within the data region are designed to be read from left to right, starting on the top row, immediately after the lengthdefining character. The maximum characters in the data region are 928.

Page mode
Page mode is one of two modes that the A776 printer uses to operate. Standard mode is typical
of how most printers operate by printing data as it is received and feeding paper as the various
paper feed commands are received. Page mode is different in that it processes or prepares the
data as a “page” in memory before it prints it. Think of this as a virtual page. The page can be any
area within certain parameters that you define. Once the printer receives the (0 × 0C) command,
it prints the page and returns the printer to standard mode.
The select page mode command (1B 4C) puts the printer into page mode. Any commands that
are received are interpreted as page mode commands. Several commands react differently
when in standard mode and page mode. The descriptions of these individual commands in this
chapter indicate the differences in how they operate in the two modes.

print the page and exit Page Mode
eject the check and select receipt
When switching between Page Mode print on the receipt and Page Mode print on the slip, 1B
40 should precede the station selection command to ensure the correct Page Mode defaults are
restored for each station.
Page size
The default page size is 200 full dots wide by 704 full dots long. (2.5” wide by 9.7” long.)
On the B780, the right side margin can be configured to .1”, .3”, or .5”. The .3” and .5” margins are for A721 emulations,
and provide a maximum width of 200 full dots. With the right side margin set to .1” the maximum width is 242 full dots
(3.024”).
On the A776, the right side margin is .1”, and provides a maximum width of 242 full dots.
The maximum length can be set to any size, but is limited by available memory. Width and length other than default
are set by command 1B 57…, with parameters specified in half dots. The length controls how much paper is fed.
For applications specifying a page size greater than 242 full dots wide, there is a configuration option for trimming
blank areas. The command is 1F 03 2F n.
Some examples of setting page size:
1B 57 00 00 00 00 90 01 80 05
0x190 = 400 half dots = 200 full dots wide
0x580 = 1408 half dots = 704 full dots long
1B 57 00 00 00 00 E4 01 F0 03
0x1E4 = 484 half dots = 242 full dots wide = 3.024”
0x3F0 = 1008 half dots = 504 full dots long = 7”
Character Size
It is best to use the Select Print Mode command (1B 21 n) to set character size. The Select Character Size command
(1D 21 n) can be used to set double wide and double high, but impact characters are not increased any further. When
using the legacy command 0x12 to set double wide, you must use the corresponding command 0x13 to turn off
double wide.

Exceptions
The Print and Reverse Feed commands (1B 4B n and 1B 65 n) are not applicable to Page Mode.
Avoid bi-directional print. Uni-directional print is the default in Page Mode.
Page mode configurations
The original implementation of Page Mode on the slip station mapped thermal dots to impact dots, and sometimes
produced output that was not acceptable to customers. Improvements have been made, and the improved impact
Page Mode is the default configuration. It is printed out on the second diagnostic page, printed via 1F 74 1F 74 double
command, or by holding down the paper feed button at power on until the second page starts to print.

Sets the position and size of the printing area in page mode.
The command can be sent multiple times so that several different print areas, aligned in different print directions, can
be developed in the printer’s page buffer before being printed using the print page mode commands (0C or 1B 0C).
Formulas
The starting position of the print area is the upper left of the area to be printed (x0, y0). The length of the area to be
printed in the y direction is set to dy inches. The length of the area to be printed in the x direction is set to dx inches.
Use the equations to determine the Value of x0, y0, dx, and dy.
• x0 = [(n1 + n2 × 256) × (horizontal direction of the fundamental calculation pitch)]
• y0 = [(n3 + n4 × 256) × (vertical direction of the fundamental calculation pitch)]
• dx = [(n5 + n6 × 256) × (horizontal direction of the fundamental calculation pitch)]

Maximum area specification in page mode
Maximizing the possible area in page mode consumes almost all of free RAM. Without any free RAM, bitmap rotations
and enlargements cannot be performed. Use the user storage status command (1D 97 m n) to determine the amount
of free memory.

29 36 nL nH
Sets the absolute vertical print starting position for buffer character data in page mode. The absolute print position is
set to [(nL + nH × 256) × (vertical or horizontal motion unit)] inches.
The vertical or horizontal motion unit for the paper roll is used and the horizontal starting buffer position does not
move.
The reference starting position is set by select print direction in page mode (1B 54). This sets the absolute position in
the vertical direction when the starting position is set to the upper left or lower right; and sets the absolute position in
the horizontal when the starting position is set to the upper right or lower left. The horizontal and vertical motion unit
are specified by the set horizontal and vertical minimum motion units (1D 50) command.
The set horizontal and vertical minimum motion units (1D 50) command can be used to change the horizontal and
vertical motion unit. However, the value cannot be less than the minimum horizontal movement amount, and it must
be in even units of the minimum horizontal movement amount.
Formulas
[(nL + nH × 256) × (vertical or horizontal motion unit)] inches.
Exceptions
This command is effective only in page mode.
If the [(nL + nH × 256) × (vertical or horizontal motion unit)] exceeds the specified printing area, this command is
ignored.

Sets the relative vertical print starting position from the current position. This command can also change the
horizontal and vertical motion unit. The unit of horizontal and vertical motion is specified by this command.
1. This command functions as follows, depending on the print starting position set by select print direction in page
mode (1B 54):
2. When the starting position is set to the upper right or lower left of the printing area, the vertical motion unit (y) is
used.
3. When the starting position is set to the upper left or lower right of the printing area, the horizontal motion unit (x) is
used.

Starts or ends macro definition. Macro definition begins when this command is received during normal operation and
ends when this command is received during macro definition. The macro definition is cleared, during definition of the
macro when the execute macro (1D 5E) command is received.
Normal printing occurs while the macro is defined. When the power is turned on the macro is not defined.
The defined contents of the macro are not cleared by the initialize printer (1B 40), thus, the initialize printer
(1B 40) command may be used as part of the macro definition.
If the printer receives a second select or cancel macro definition (1D 3A) command immediately after previously
receiving a select or cancel macro definition (1D 3A) the printer remains in the macro undefined state.
Formulas
The contents of the macro can be defined up to 2048 bytes.

Value of r:
The number of times to execute the macro.
Value of t:
The waiting time for executing the macro.
Executes a macro. After waiting for a specified period the printer waits for the paper feed button to be pressed. After
the button is pressed, the printer executes the macro once. The printer repeats this operation the number of specified
times.
When the macro is executed by pressing the paper feed button (m = 1), paper cannot be fed by using the paper feed
button.
Formulas
The waiting time is t × 100 ms for every macro execution.
m specifies macro executing mode when the LSB (least significant bit) m = 0
The macro executes r times continuously at the interval specified by t when the LSB (least significant bit) of
m = 1.
Exceptions
If this command is received while a macro is being defined, the macro definition is aborted and the definition is
cleared.
If the macro is not defined or if r is 0, nothing is executed.

Notes:
All parameters are ASCII characters, i.e. greater than or equal to 0x20, with the exception of a non-ASCII character
enclosed in single quotes as a field separator. This applies both to parameter specifications sent from application to
printer, and to MICR data returned from printer to application.
Parameters are positional; their order in the parameter string is the order in which the parsed MICR data will be
returned. Unrecognized parameters will be ignored, and processing of the parsing parameters will stop. Any data
remaining after the unrecognized parameter will be treated as normal input data.
If parameters are not defined (for example, 1B 77 50 <CR> or 1B 77 70 <CR>) parsing is not selected. One status byte
followed by all decoded MICR characters will be returned. The chart on the next page is the default parsing format if no
other is selected:

number in these spots, using the following ordered algorithm. The examples use letters to represent symbols on the
check:

Transit symbol
“on us” symbol

Check serial number
Any other number
A number bracketed by “on us” symbols in the auxiliary “on us” field is the check serial number.
occcccco txxxxxxxxxt xxxxxxxxo
Otherwise, a three or more digit number to the right of the rightmost “on us” symbol, and to the left of the leftmost
amount symbol if an amount field is present, is the check serial number.
txxxxxxxxxt xxxxxxxxo cccc
txxxxxxxxxt xxxxxxxxo cccc $xxxxxx$
If both of these searches fail to produce the check serial number, extract the whole account number field from
between the rightmost transit symbol and the rightmost “on us” symbol. A three, four, or five-digit number to the right
of the rightmost transit symbol, separated by a space or a dash from the rest of the account number is the check serial
number.
txxxxxxxxxt cccc xxxxxxxxo
txxxxxxxxxt cccc-xxxxxxxxo
txxxxxxxxxt cccc xxxxxxxxo xx
If all of these searches fail to produce the distinct check serial number, and the check serial number field has been
specified in the parsing parameter string options, no check serial number will be returned. If it is imbedded within the
account number field, it will be returned as part of that variable length field.
Exceptions
Some banks print the check serial number in a location that cannot be electronically distinguished without specific
exception information, although it can be visually distinguished because it is repeated in the upper right corner of
the check. For these cases, the printer can hold up to nine exceptions for specific banks in its non-volatile memory
(NVRAM), which is accessed by the read and write NVRAM commands. The specific bank is picked out by its transit
number, and the firmware will look in the exception table for a transit number match before looking in the normal
check serial number locations.
In this example, without an exception table entry, the firmware would always pick the rightmost four-digit number as
the check serial number following rule two above. The bank with the three digit check serial number and the four digit
extension after the “on us” symbol would need to be exceptionally recognized:
txxxxxxxxxt ccc-xxxxxxxxxxoxxxx
txxxxxxxxxt xxx-xxxxxxxxxxocccc
In this example, without an exception table entry, the firmware would not be able to pick out the check serial number
because it is not separated from the rest of the account number:
txxxxxxxxxt ccccxxxxxxxxxxo
In this example, without an exception table entry, the firmware would not be able to pick out the check serial number
correctly, because it is imbedded within the rest of the account number:
txxxxxxxxxt xxx-ccc-xxxxxxxxxxo

Loading the exception table
The exception table begins at word 20 in NVRAM. Each entry takes five words. There is room for eight exceptions. An
application can load local exceptions into the printer using the write NVRAM command:
0x1B 0x73 n1 n2 k
which writes the two byte word n1:n2 to word k in NVRAM.
Exception table entry format
Each exception table entry consists of five words. The first two words contain the first eight characters of the transit
number by packing the low order nibble of the numeric transit number characters. For Canadian checks, eliminate the
dash and store the eight numerics.
The next three words are used as six individual bytes to tell the firmware how to interpret the MICR characters that fall
to the right of the rightmost transit symbol. Each of the six bytes is positional and consists of two parts: character type
and number.
The three high order bits of each byte mark the character type. The characters can be marked in three ways: check
serial # character, account # character, or “skip this character or symbol.”
The five low order bits of each byte contain the number of characters of that type to extract. Most exceptions will not
need to use all six bytes; in that case clear the unused bytes to zero.

0x1B 0x73 0x12 0x34 25
0x1B 0x73 0x56 0x78 26
After the right transit symbol are immediately the four characters of the check serial #, followed immediately by the
ten characters of the account number. These would be bitwise encoded as:
and
0 0 1 0 0 1 0 0 (check #, four characters)
0 1 0 0 1 0 1 0 (account #, 10 characters)

0x1B 0x73 0x22 0x13 30
0x1B 0x73 0x76 0x32 31

0x1B 0x73 0x82 0x24 33
0x1B 0x73 0x00 0x00 34
Maintaining the exception table
Present contents of the exception table can be examined using the read NVRAM command:
0x1B 0x6A k
which reads and returns word k in NVRAM. When the exception table is full, a new entry can replace an older, less
frequently used entry, by merely rewriting the words for that table entry.

See also command “Expanded flash memory allocation” (1D 22 80...) and “Select flash area” (1D 22 81 n).
Important: While erasing flash memory, the printer disables all interrupts, including communications. To provide feedback
to the application, the printer responds to the application when the erase is complete with a 0D (Hex). After sending the
erase user flash sector (1D 40 n) command, an application should wait for the response from the printer before sending data.
Otherwise, data will be lost. If an application is unable to receive data, it should wait a minimum of ten seconds after sending
the erase user flash sector (1D 40 n) command before sending data.

n = 0 gets largest free block size
n = 1 gets the total size free
m = 3
return the CRC of a logo indexed by n
m=5
return the CRC of a macro that has been stored, n = 0
m = 0
the value of n selects a return of either the largest free block or total free size, since contiguous allocation cannot
be assumed as this area is completely under user control through address parameters.
n=0
if only one instance of an object type is allowed (macro, user data, user defined characters).
n
is the item index when more than one object of type m is possible
n <= FE, see the comments about logo and character set indexes
n = FF : return a list describing all the existing items of type m
Note: When a specific item request is made, a returned CRC value of 0 0 indicates that no item is stored at that index. There
is a practically negligible possibility that a valid object will have a 0 0 CRC; if this is of concern, applications should check the
object downloaded byte sequence to verify that this is not the case (as well as store the CRC as an “ID” for the object if needed
later for return value comparisons).
Downloaded character sets are identified by integer extending the existing code page selection as enumerated in the
select international character set (= select character code table) command. The firmware standard list is incrementally
extended each time a new single or double byte set is downloaded.
Single byte downloaded fonts are selected by
m = 3 and 0x40 <= n < 0x80.
Since there are only three double-byte character sets supported, the value 0x80 / 0xA0 / 0xC0 selects the first, second,
third downloaded double byte font respectively. In return, each downloaded double byte character band is reported
individually as 0xC0, 0xC1, 0xC2 ….for as many bands as have been defined.
This command returns the state of occupancy of available flash storage and user RAM. The printer response for each
item is a 4 byte header, 0x1D 0x97 nL nH (number of bytes that follow in the response) and for each item a
4 byte structure: 1st m (type) byte, 2nd n index byte followed by a 2 byte CRC in Lo Hi order of the data string in that
storage space.
The return for m = 0–2 is the header and one 4-byte item giving remaining storage space in the CRC position in
Lo Hi order: 1D 97 4 0 m 0 fL fH, where f is the kBytes of storage remaining. Note that RAM storage space is not content
typed, while available flash is statically divided into logo, character set, and user data types. Change of the divisions is
possible via flash erasure and flash
allocation commands.
If the communication protocol is RS-232C – Xon/Xoff, then “X symbol substitution response” should be configured with
the setting communications parameters command (US STX , 1F 02).

Flash download
These commands are used to load firmware into the printer.
The commands are listed in numerical order according to their hexadecimal codes. Each
command is described and the hexadecimal, decimal, and ASCII codes are listed.
There are three ways to enter the download mode.
1. Powering the printer up with DIP Switch 1 up.
2. While the printer is running normally, send the command, “Switch to flash download mode”
(1B 5B 7D) to leave normal operation and enter the download mode.
3. If the flash if found corrupted during level 0 diagnostics the download mode is automatically entered after the
printer has reset.
The printer never goes directly from the download mode to normal printer operation. To return to normal printer
operation either the operator must turn the power off and then on to reboot or the application must send a command
to cancel download mode and reboot. DIP switch 1 must in UP position during reboot to return to normal printer
operation.
When each flash download command is received, the printer returns either ACK or NAK to the host computer when
each command is received:
• ACK (hexadecimal 06)
Sent when the printer has received a host transmission and has completed the request successfully.
• NAK (hexadecimal 15)
Sent when a request is unsuccessful.
Communicates to the printer information downloaded from applications. Data is downloaded to flash memory to
query the state of the firmware, calculate the firmware CRC and other functions.

Graphics Commands
These commands are used to control the way graphics are entered or printed. They are listed in numerical order of their
hexadecimal codes.
Graphics
Enters graphics printing mode which prints all available dots (uses all wires in the printhead). Any combination of
dots may be printed in a graphics cell. Each graphics cell is eight dots wide by nine dots high, with nine bytes of data
needed to define the cell (each byte defines the row of eight dots). The command must precede the nine bytes that
define the cell. Graphics and text may be printed on the same line.
Do not use the command again to turn off this graphics mode as the printer will expect another set of bytes to define
a new cell.

Each line may have up to 25 graphics cells (full-dot graphics). The print line is printed unidirectionally.
Use six Vertical Tab commands (0B) or one Line Feed command (0A) between each line (8 lines/inch).
Graphics: 5 Dot
Enters or exits graphics printing mode which prints only the top five dots of the column (corresponding to the top five
wires of the printhead). These top five dots correspond to the least significant five bits (bits 0-4) of the data sent to the
printer as shown in the table.

Each byte of data sent defines each column of the graphic to be printed. The first byte defines the column in the left
margin, with the following bytes defining the columns to the right, for a total of up to 200 columns in the print line.
The print line is printed unidirectionally. Graphics and text may be printed on the same line.
Use three Vertical Tab commands (0B) to overlap printing by half a dot with the next line. Each vertical tab advances
the paper by 0.02083 inches, with three tabs advancing the paper by 0.062 inches.
Note: This DH printer command provides compatibility with earlier DH model printers. It is generally not used for new
applications. See the Graphics command (1E) for the more generally used command.
Printer Status Commands

Appendix C: Electronic Journal
The Electronic Journal feature is for use with an application that does not support electronic journal. The printer
can be used to store a variety of transactions.
Electronic Journal Storage
There are two methods for activating Electronic Journal:
1F 03 18 01 n Auto Journal Mode via Configuration Command:
Value of n
1
2
3
4
5
6
7
Data saved in journal
Receipt
Slip
Validation
Receipt and slip
Receipt and validation
Slip and validation
Receipt, slip, and validation
•
The printer can be configured to power up in Auto Journal Mode using command 1F 03 18
01 n. Any combination of print stations can be configured. This configuration is saved over
power cycle. The electronic journal configuration information is printed on the second
diagnostic page.
•
Most commands and data printed are saved in the journal flash buffer.
•
Logos and graphics printed on the receipt are not saved in the journal flash buffer.
•
Multiple line feeds are not saved in the journal flash buffer.
•
A knife cut sent to the receipt is saved in the journal flash buffer as two print commands:
0x0A 0x0A.
Auto Journal Mode via Runtime Command:
1F 0A C1 - Enable
1F 0A C2 - Disable
Commands and data printed on the receipt only are stored in the Journal flash buffer.

A776 (B780) Programming Guide

Appendix C: Electronic Journal
Journal RAM buffer
Journal data is temporarily buffered in RAM until the printer is triggered to write it to flash. At power up 4K bytes
of RAM will be dynamically allocated. In the unlikely event that 4K bytes are not available, 2K will be allocated. If
for some reason 2K bytes are not available, the electronic journal feature cannot be used. Allocation success or
failure information is available to the interface via commands described below.
Loss of power results in loss of any data currently in the journal RAM buffer.
Triggers that cause the journal data in RAM to be written to flash are:
•
Knife Cut command
•
Write Journal RAM Data to Flash command (described below)
•
Printer is idle for 10 seconds
•
Reset Printer command (0x1D 0xFF)
•
Print To Journal command (described below)
•
RAM becomes filled before one of these other triggers occurs.
The printer goes busy at the communication interface while writing to the journal flash buffer.
Journal Flash buffer
A portion of flash memory is available for the journal flash buffer. By using the Flash Memory User Sectors Allocation
command (0x1D 0x22 0x 55 n1 n2), the user can allocate the number of 64Kbyte sectors used for logos, user storage,
and journal flash buffer.
If there are X sectors available, the Flash Memory User Sectors Allocation command will allocate n1 sectors to logos,
n2 sectors to user storage, and (X – n1 – n2) sectors for the journal flash buffer. If all available sectors are allocated for
logos and user storage, there is no flash available for the journal.
The firmware default allocation is 1 sector for logos, 1 sector for user storage, and the rest for journal, but this may
be changed at printer build time. Journal flash allocation and flash usage information is available via commands
described below, and is printed on the diagnostics form.
Before erasing flash, check to see if there is journal data stored, and print it out if necessary.
Triggers that cause the journal flash buffer to be cleared are:
•
Clear Journal command (described below)
•
Flash Memory User Sectors Allocation command (0x1D 0x22 0x 55 n1 n2) reallocates flash
memory.
•
New Flash firmware is downloaded to the printer
•
Exception Conditions in Auto Journal Mode
When there isn’t enough memory available in the journal flash buffer, the printer beeps at each receipt to signal the
flash full condition. The printer will print a duplicate receipt and cut after it, instead of writing it to flash, and clear
out the RAM buffer. When the trigger for writing to flash is a knife cut (which would be the usual case in Auto Journal
Mode) the customer receipt is easily detached from the duplicate receipt by the operator.
If a receipt is over 4Kbytes in size, and there are less than 4Kbytes available in the journal flash buffer, the printer will
not print a portion of the duplicate receipt in the middle of the original receipt. This portion of the duplicate receipt is
lost.

Printing and Erasing the Journal Flash Buffer:
Operator Activation of Journal Print and Erase
Enabled via 1F 03 2E 01. Disabled via 1F 03 2E 00. Enabled and disabled also via the config menu under the
Emulation/Software Options sub-menu. Default is disabled. Option prints on diagnostic Form II:
Journal print via Command Only
(when disabled)
Journal print via Operator
(when enabled)
Printing Journal via Operator (when enabled):
1) Open the receipt cover.
2) Press the paper feed button three times quickly, about a half second each. A short tone will sound each time. If you
press the feed button too long, or wait too long between depressions, a longer tone will sound and the sequence is
aborted; you have to start over.
3) Close the receipt cover.
If there is nothing in the journal, the message “No Flash journal” prints out on the receipt. If there is something in the
journal, it prints on the receipt, followed by a query to the operator printed on the receipt:
Erase journal?
1F 0A C3
Yes --> Long click
No --> Short click
Clear Journal
Erases the journal flash buffer. Printer goes busy at the communication interface while the flash is being erased.
Application should not send any further data or commands until printer goes not busy at the communication
interface. Printer returns a 0x0D when the erase is complete. At this point the application can resume sending data to
the printer.
1F 0A C4
Print Journal
Prints contents of journal data saved in flash. Printer goes busy at the communication interface. Application should
not send any further data or commands until printer goes not busy at the communication interface. If paper runs out,
printing will pause until a new roll is loaded, then resume where it left off.
Points to note when printing the journal:
•
Receipt character attributes and bar code attributes are set to their default values before
and after printing the journal.
•
Receipt station is selected.
•
Macro definitions are not cleared.
•
If the macro execution command is in the journal, the macro definition should be in the
journal also. If not, the printed journal might look OK before a power cycle when the
macro definition is still in memory. After a power cycle the macro definition will be gone.
•
If User Defined characters are printed, their definitions (0x1B 0x26 ….) should be stored in
flash (via 0x1D 0x22 0x33) and their selection command (0x1B 0x25 0x01) should be in the
journal buffer.
