Chapter 1: About the Printer
Introducing the A758 Printer
The A758 is an extremely fast, quiet, and reliable point-of-sale printer. It consists
of two specialized printers in one compact package: a thermal printer on top that
prints receipts, and an impact slip printer in front to print on forms and checks
that you insert. The thermal printer is optimized for ease-of-use in busy
environments. There is no ribbon or ink cartridge to change, and you load the
paper by simply dropping in a new roll. The impact printer provides the power
and flexibility necessary to print on checks or multi-part forms up to five plies, in
a wide variety of sizes and orientations.
The A758 easily fits in anywhere. It connects to any host computer that uses the
standard RS-232C interface. Other interfaces are also available. The printer’s
standard command set allows it to work with software written for Axiohm, or
other ESC/POS™ compliant printers. A variety of sensors enable the printer to
communicate its status, and the printer’s journal is kept electronically by the host
computer.
Several state-of-the-art check-handling options are also available. The Magnetic
Ink Character Recognition (MICR) option enables the printer to read the special
codes printed on checks and send this information to the host computer to verify
the check. The Check Flip option saves transaction time by making check
handling a one-step process—after reading the front of the check and printing on
the back, the printer is able to flip the check over and print on the front of the
check.
This section describes the printer’s features and options in more detail.

The set of options installed on a particular printer can be determined by looking
at the printer's model number. The printer's model number appears on a label on
the right side of the printer. Four-digit model numbers are assigned to the
various A758 models based on the following formula:
♦
The first digit indicates the release vintage and color of the printer's case.
♦
The second digit indicates the amount of flash memory installed in the
printer.
♦
The third digit indicates whether the printer has the MICR and/or check flip
features.
♦
The fourth digit indicates whether the printer has a knife for cutting receipts.
For example, a printer with model number A758-1015 has a standard color case,
512K of flash memory, the MICR feature, and a knife for cutting receipts.

The A758 printer takes up relatively little counter space and may be set on or
near the host computer. With the RS-232C interface, you can place the printer up
to 50 feet from the host computer and power supply.
Place the printer on a level surface, and make sure there is enough room to open
the receipt cover to change the paper and to open the front cover to change the
impact printer’s ribbon cassette. Leave several inches around the printer for
connecting and accessing the cables.
If the printer has an optional Magnetic Ink Character Recognition (MICR) check
reader installed, you may need to make additional adjustments to the printer’s
location. Because devices such as CRT monitors or large metal surfaces affect the
printer's magnetic field, they can cause intermittent check reading errors.

Changing the Receipt Paper
Change the paper when either a colored stripe appears on the receipt paper or
the printer’s On Line, Paper Status, Error LED slowly flashes (indicating that
15 + 10 feet of paper remains on the roll). Change the paper as soon as possible to
avoid running out of paper part way through a transaction.
If the On Line, Paper Status, Error LED blinks fast, the paper is out. Change the
paper immediately or data may be lost. The printer will not operate without
paper, but it may continue to accept data into memory from the host computer.
Because the printer cannot print any transactions, this data in memory may be
lost.

Emulation/Software Options
Printer Emulations
Printer emulations determine the commands that are available to the printer.
They are set by using the Configuration Menu. (See “Configuring the Printer” for
instructions on how to enter the Configuration Menu.) The available options are:
♦
A758 Native (enables all new functions)
♦
A756 Emulation (for use with legacy software)
Printer ID Mode
This switch is used to determine what Printer ID value is returned in response to
a Transmit Printer ID (1D 49 01) when the printer is in A756 Emulation Mode.
The printer can be configured to send back the ID of the A758 or the A756.

This function allows the user to set the default lines per inch printed by the
thermal receipt printer to 6, 7.52 or 8.13. (See “Configuring the Printer” for
instructions on how to enter the Configuration Menu to change this setting.)
Carriage Return Usage
This function allows the printer to ignore or use the Carriage Return
(hexadecimal 0D) command depending on the application. Some applications
expect the command to be ignored while others use the command as a print
command. (See “Configuring the Printer” for instructions on how to enter the
Configuration Menu to change this setting.)
Hardware Options
Print Density
This function makes it possible to adjust the energy level of the printhead to
darken the printout. An adjustment should only be made when necessary. The

Chapter 3: Using the Printer
Basic Troubleshooting
The A758 printer is a simple, generally trouble-free printer, but from time to time
minor problems may occur. For example, the power supply may be disconnected
or the thermal printhead may overheat.
The On Line, Paper Status, Error LED on the operator panel may signal that
something is wrong. The light on the front right side of the printer is used only to
indicate when a form is inserted properly. It does not indicate an error.
For some problems, the printer communicates the information to the host
computer and relies on the application to indicate what the problem is.
The information on the following pages describes some problems that you may
encounter: problems that you can easily fix, and others that you will need to
contact a service representative for.
You may be able to correct many of the conditions or problems without calling
for service. However, if a problem persists, contact a service representative. See
“Contacting a Service Representative” at the end of this chapter.
If something is wrong with the printer, take the following general steps:
♦
Cycle the power of the printer and note its behavior.
♦
Check the On Line, Paper Status, Error LED and compare its behavior to the
table below.

Considerations for glued edges on slip paper:
1.
No glue on bottom edge.
2.
Right or top edge: Paper feeding and insertion affected by gluing method,
length of edge, and quality of glue used.
3.
Left edge or wide slip paper: Skewing may occur.

The Slip/LED Sensors use a reflective photo sensor.
♦
Do not use paper that has holes or is translucent at the Slip/LED Sensor
location. (See “A” in above illustration.)
♦
Do not use paper that has holes on dark areas with low reflection (less than
60% reflection) at the Slip Sensor location. (See “B” in above illustration.)
♦
Thin paper should be used between the top and bottom sheets of multi-ply
paper. Thick paper reduces the copy capability.
MICR Reader – Additional Information
♦
The check must be flat and void of curls, folds, or wrinkles (especially at the
edges). Wrinkled checks may rub against the ribbon causing them to become
ink-stained.
♦
Checks must be void of clips or staples. Paper jams, MICR read errors,
and/or MICR head damage could occur.
♦
Immediately release the check once the printer starts to feed it. Failure to
release the check could skew it, causing paper jams and MICR read errors.

Slip Media
The A758 prints 1 to 5 part forms with the following limitations:
♦
The minimum thickness of a single part form is .08 mm (.003 inch).
♦
If present in a multi-part form, cardstock will be the bottom part.
♦
Maximum total thickness is .40 mm (.016 inch).
♦ Minimum form reflectivity is 60%
Minimum form length (feed direction) for forms inserted from the front up to the
slip stop is 68 mm (2.68 inches) w/o check flip option and 70 mm (2.75 inches)
w/Flip option. Minimum form width (print direction) is 51 mm (2.00 inches).
These minimums ensure the form covers both optical slip detectors, and expose
about one inch of the form to push in place.
The form must be at least 127 mm (5.00 inches) wide to print all 66 standard or 80
compressed columns. Large forms may be inserted from the left side and
override the slip stop. Forms over 170 mm (6.70 inches) wide will extended
outside the left side of the printer.

Migration
The A758’s standard command set allows it to work with software written for
Axiohm or other ESC/POS™ compliant printers.
The A758 supports two modes of operation: “A756 emulation” and “A758
native” modes. When the A758 is configured for A756 emulation mode through
the Configuration Menu, the printer is backward compatible to A756 slip and
receipt applications (no journal) except that receipt print resolution is increased
from 6 to 8 dots/mm. If the 6 to 8 dot/mm conversion feature is not used, this
will result in the size of graphics being reduced by 25%.
See Chapter 7: Programming Guide for a comparison to the A756.

Performance Requirements
Slip Printing
Slip Positioning
Forms are inserted from the front, top-of-form first, up to a form stop behind the
carriage, or inserted from the left side and over-ride the form stop. In each case
the form must be aligned with the check guide (right edge of the slip path). A
pair of optical sensors are located (a) 11 mm (.45 inch) above the print centerline
and 25 mm (1.00 inch) from the check guide, and (b) just inside the check guide
and 37 mm (1.45 inches) below the print centerline. The application can use these
for form-in and trailing edge detection. A green slip-in LED indicates when both
detectors are covered.
The application moves the form bi-directionally in 1/72-inch increments to
position the first line of print.

A solid black line is 100% dot coverage.
In order for an application to achieve the fastest throughput it must ensure that
data arrives at the printer at least as fast as it is printed, so the printer will be able
to print each line after the preceding line, without stopping to wait for more data.
Ideally, an application will send all the data for an entire customer receipt
without pausing between characters or lines transmitted.

Chapter 6: Communiction Interface
Communication Overview
In order for the printer to communicate with the host, a communication link must
be set up. The A758 printer supports either the RS-232C or the IEEE 1284 parallel
communication interfaces. Other communication interfaces may be available as
options.
The RS-232C interface has a protocol associated with it that the host must
understand and adhere to. Only when the interface parameters match and the
proper protocol is used will the host and the printer be able to communicate.
Once the communication link is established, commands can be sent to the printer.
This section describes how to send commands to the printer using DOS and
BASIC. This section does not take into account the necessary protocol, but is
meant as a general introduction to how the printer functions.
Using DOS to Send Commands
One way of getting commands to the printer is to send them directly from DOS.
For example, assuming that the printer and computer are set to the same
communications parameters, the command:
COPY CON: COM1:
sets the computer up such that the hexadecimal code corresponding to any key
that was pressed would be sent to the communication port COM1 when the
COPY mode is exited. If the printer is connected to COM1, then the data will go
to the printer.
Exit the COPY mode by typing:
CTRL Z
and then pressing the ENTER key. Once the computer knows to direct data from
print commands to the proper port, commands can be sent from any software
program.
Using BASIC to Send Commands
In BASIC, printer commands are sent as a string of characters preceded by the
LPRINT command. For example:
LPRINT CHR$(&H0A)
sends the hexadecimal number 0A to the printer, which causes the printer to
print the contents of its print buffer. Commands sent prior to 0A tell the printer
exactly how data should appear on the paper. For example:
LPRINT CHR$(&H12); "ABC"; CHR$(&H0A)
sends the hexadecimal numbers 12 41 42 43 0A to the printer. This causes the
printer to set itself to double wide mode (12), load the print buffer with “ABC”
(41 42 43), and finally, print (0A). Again, the communication link that the BASIC
program configures to must be matched to that of the printer.
September 1999

A758 Owner’s Guide
Chapter 6: Communiction Interface
RS-232C Interface
The RS-232C interface uses either the XON/XOFF (software) or DTR/DSR
(hardware) protocol to control the flow of information between the computer and
the printer. For XON/XOFF, a particular character is sent back and forth between
the host and the printer to regulate the communication. For DTR/DSR, changes
in the DTR/DSR signal on the RS 232 interface coordinate the information flow.
The RS-232C interface offers standard settings that are selected with the
Configuration Menu. Use of the Configuration Menu is described in
“Configuring the Printer” in this manual.
Print Speed and Timing
The fast speed of the printer requires the application to send data to the printer at
least as fast as it is printed. The application must also allow output lines to be
buffered ahead at the printer, so the printer will be able to print each line
immediately after the preceding line, without stopping to wait for more data.
Ideally, the application will send all the data for an entire receipt or slip without
pausing between characters or lines transmitted.
If the application sends data at 9600 baud and pauses between lines for as short a
time as 50 milliseconds, the printer will never be able to print at full speed.
However, if the application sends data at 19.2 K baud and does not pause
between lines, the printer will be able to print at its full speed of 2400
lines/minute. The table below shows that with a pause of 50 milliseconds after
each line, the transmit time equals or exceeds the printer process time, slowing
down the printer, regardless of the baud rate.

* Process Time is the time it would take the printer to process the data if all
transmitted data was present. (It is not the time it takes to print the receipt.)
Example: 20 characters/line, with 20 lines = 0.5 seconds process time for the
printer. It takes 1.2 seconds to send the data to the printer at 19.2K-baud speed
with a 50ms delay after each line. Thus the printer would have to wait 0.7
seconds longer to receive the data than it could process it if no delays existed and
the transmission speed were faster.
September 1999

A758 Owner’s Guide

RS-232 Communications
The A758 offers an industry standard RS-232 serial point-to-point interface, with
options available to the user.
Options that may be set through the Configuration Menu are:
♦
The baud rate of 115200, 57600, 38400, 19200, 9600, 4800, 2400, or 1200 baud
♦
The number of data bits to seven or eight
♦
The number of stop bits to one or two
♦
Enable or disable parity
♦
The flow control to software (XON/XOFF) or Hardware (DTR/DSR)
♦
Set the printer to ignore data errors or print a “?” upon encountering an error
RS-232 Interface Timing
Receiving data, DTR/DSR or XON/XOFF selected:
[DTR MARK]
- Between power on and ready to accept data.
- In an error state.
- Remaining space in the 4K buffer falls below 256 bytes. *
[DTR SPACE]
- When ready to accept data.
- Remaining space in the 4K buffer rises above 512 bytes. **
[XON sent]
- When ready to accept data after power on.
- Remaining space in the 4K buffer rises above 512 bytes. **
[XOFF sent]
- In an error state.
- Remaining space in the 4K buffer falls below 256 bytes*
* - 10 bytes in line mode.
** - 20 bytes in line mode.
Sending data (status):
In DTR/DSR mode, data is sent only when DSR is SPACE.
In XON/XOFF mode, DSR state is ignored.
September 1999

A758 Owner’s Guide
Chapter 6: Communiction Interface
XON/XOFF Protocol
The XON/XOFF characters coordinate the information transfer between the
printer and the host computer. The printer sends an XON character when it is
ready to receive data and it sends an XOFF character when it cannot accept any
more data. The software on the host computer must monitor the communication
link as shown in the following flowchart in order to send data at the appropriate
times.
If XON/XOFF has been selected, the printer also toggles the DTR signal, as
described in the next section, but it does not look at the DSR signal to transmit
data.
Host Flow Control Diagram
XON character = hexadecimal 11.
XOFF character = hexadecimal 13.
DTR/DSR Protocol
The DTR signal is used to control data transmission to and from the printer. It is
driven low when the printer is ready to receive data and driven high when it
cannot accept any more data. Data is transmitted from the printer after it
confirms that the DSR signal is low.

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. Any of the commands may be used in any
combination to program a host computer to communicate with the printer
(unless otherwise noted).
Some commands listed and described here may not be implemented. They will
be identified as “not implemented”. If received, they are ignored and not sent to
the print buffer as data. Any non-legal commands are sent to the print buffer as
data.

Comparison to A756
New Features
There are a number of new firmware features in the A758 Native Mode. These
include:
♦
Page Mode on the receipt
♦
Additional Code pages
♦
Additional character attributes
♦
Flip
♦
More flexible handling of User-defined Characters and Logos
(Downloadable Bit Image)
♦
Higher baud rates
♦
8 High graphics on slip
♦
Macro capabilities
♦
Additional remote diagnostics
Page Mode on the receipt
Normally the printer will print data as it is sent. In Page Mode, the data to be
printed is composed on a page before printing. This composition process gives
the application developer the ability to mix text, graphics and barcodes in
different orientations and locations. Once the page composition process is
completed, the page is printed. See the Page Mode commands in this section.
Additional Code pages
The A758 includes support for the additional Code pages: CP852, CP858, CP860,
CP863, CP865 and CP866.
Additional character attributes
The A758 includes support for additional character attributes including Bold,
Italics, Underline, Black/White Reverse Print, Superscript, Subscript, and
Scaling.
Flip
The A758 can flip a check on command.
Additional flexibility when using User-defined Characters and Logos
(Downloadable Bit Image)
The A758 can process User-defined Characters and Logos simultaneously. These
items are stored in FLASH or SRAM, depending on the application developer’s
preferences.
September 1999

A758 Owner’s Guide
Chapter 7: Programming Guide
Barcodes
The A758 supports printing of one-dimensional barcodes on the slip station. The
receipt station supports ladder barcodes and the addition of Code 93 and
PDF417.
FLASH Memory Allocation
The application developer has the ability to determine how the FLASH Memory
is allocated between the User Data Storage and Logos/User-defined Characters.
Higher Baud Rate
The A758 now supports serial communication rates of 57,600 and 115,200.
8 Dot High Graphics on Slip
In A758 Native Mode, the slip supports graphics that are 8 dots high. In A756
Emulation Mode, the graphics are 7 dots high.
Macro Capability
The A758 supports the ability to record and execute a series of commands called
a macro.
Additional Remote Diagnostics
The A758 supports 5 additional remote diagnostics.
1.
Number of Flash cycles
2.
Number of knife jams
3.
Numbers of cover openings
4.
Maximum thermal printhead temperature
5.
Number of slip lines printed

Comparison Chart
The following table details the list of commands whose behavior differs from the
A756 because of the physical differences of a 6 dots/mm head (A756) versus an 8
dots/mm head (A758).
Command
Description
Difference between A756 and A758
configured in A756 Emulation Mode.
15 n
Feed n Dot Rows
This command will move the paper on the receipt
in n/203 inch steps instead of n/152 inch steps.
16 n
Add n Extra Dot Rows
The dot rows will be measured in n/203 inches
versus n/152 inches.
1B 20 n
Set Right-Side Character
Spacing
This command sets the right side spacing to “n”
horizontal motion units. By default, these units
are in terms of 1/203 inches versus 1/152 inches.
1B 24 n1 n2
Set Absolute Starting
Position
For graphics commands, the position is scaled to
best match the previous product. In text mode, the
equivalent character position is calculated.
1B 26 s c1 c2 n1 d1...nn dn]
Define User-Defined
Character Set
Since the dots on the new printhead are smaller,
user-defined characters that were used on the
previous printer will appear smaller on the new
printer.
1B 2A m n1 n2 d1...dn
Select Bit Image Mode

Moves the print position to the next tab position set by the Set Horizontal Tab
Positions (1B 44 n1 n2 ... 00) command. The print position is reset to column one
after each line.
Tab treats the left margin as column one, therefore changes to the left margin will
move the tab positions.
When there are no tabs defined to the right of the current position, or if the next
tab is past the right margin, line feed is executed (both slip and receipt.) HT has
no effect in page mode. Printer initialization sets 32 tabs at column 9, 17, 25, …

Integer after dividing n by 256.
The values for n1 and n2 are two bytes in low byte, high byte word orientation.
Sets the print starting position to the specified number of dots (up to the right
margin) from the beginning of the line. The print starting position is reset to the
first column after each line.
Formulas:
Determine the value of n by multiplying the column for the absolute starting
position by 10 (slip, or receipt standard pitch) or 8 (receipt compressed pitch).
The example shows how to calculate column 29 (10 dots per column) as the
absolute starting position.
28 x 10 = 280 dots (beginning of column 29)
280/256 = 1, remainder of 24
n1 = 24 n2 = 1

Set Horizontal Tabs
ASCII:
ESC D [n] k NUL
Hexadecimal: 1B 44 [n] k 00
Decimal:
27 68 [n] k 0
Value of n:
Column for tab minus one.
n is always less than or equal to the current selected column
width.
Value of k:
0 - 32
Default:
Every 8 characters from column. 1 (9, 17, 25, etc.) for normal
print.
Sets up to 32 horizontal tab positions n columns from column one, but does not
move the print position. See the Horizontal Tab (09) command.
The tab positions remain unchanged if the character widths are changed after the
tabs are set. This command ends with hexadecimal 00; hexadecimal 1B 44 00
clears all tabs. Tabs assumed to be in strictly ascending order. A tab out of order
terminates the command string as if it were 00, and remaining tab values are
taken as normal data.
Formulas:
Set the tab positions in ascending order and put Hex 00 at the end.
Hex 1B 44 00 (number of tabs not specified) clears all tab positions.
Exceptions:
The tabs cannot be set higher than the column width of the current pitch.
Set Relative Print Position
ASCII:
ESC \ n1 n2
Hexadecimal: 1B 5C n1 n2
Decimal:

Value of n:
To Move the Relative Starting Position Right of the Current Position by n dots:
n1 =
Remainder after dividing n by 256.
n2 =
Integer after dividing n by 256.
The values for n1 and n2 are two bytes in low byte, high byte word orientation.
To Move the Relative Starting Position Left of the Current Position by n dots:
n1 =
Remainder after dividing (65,536-n) by 256
n2 =
Integer after dividing (65,536-n) by 256
The values for n1 and n2 are two bytes in low byte, high byte word orientation.
Moves the print starting position the specified number of dots either right (up to
the right margin) or left (up to the left margin) of the current position. The print
starting position is reset to the first column after each line.

Formulas:
To move to the left:
Determine the value of n by multiplying the number of columns to move left of
the current position by 10 (slip or receipt standard pitch) or 8 (receipt
compressed pitch). The example shows how to set the relative position two
columns in standard pitch (10 dots per column) to the left of the current position.
2 x 10 = 20 dots (two columns to be moved left of the current position)
65,536-20 = 65516
65,516/256 = 255, remainder of 236
n1 = 236
n2 = 255
To move to the right:
Determine the value of n by multiplying the number of columns to move right of
the current position by 10 (slip or receipt standard pitch) or 8 (receipt
compressed pitch). The example shows how to set the relative position two
columns in standard pitch (10 dots per column) to the right of the current
position.
2 x 10 = 20 dots (two columns to be moved right of the current position)
20/256 = 0, remainder of 20
n1 = 20 n2 = 0
Related Information:
If the Set Horizontal and Vertical Minimum Motion Units command (1D 50) is
used to change the horizontal and vertical minimum motion unit, the parameters
of this command (Set Relative Print Position) will be interpreted accordingly. For
more information, see the description of the Set Horizontal and Vertical
Minimum Motion Units command (1D 50) in this document.
Compatibility Information (A758 receipt vs. A756 receipt)
There is a difference in the normal behavior of this command in A758 Native
Mode as compared to the original A756. The difference exists when the
command is used to move to the left. The A756 processes the whole print string
prior to putting it in the buffer for the print head. This method of processing
allows the A756 to backup in the print string and replace characters and their
associated attributes when a “Set Relative Print Position” command instructs the
printer to move the print position to the left.
In order to improve the speed of printing, the A758 moves the data into a buffer
for the printhead when it receives it. When the “Set Relative Print Position”
command contains a move to the left, this causes the new data to overstrike the
previous data. This behavior can be used to an application’s advantage to
provide the ability to create compound characters on the receipt station.

Sets the right side character spacing to [n x horizontal or vertical motion units].
Values for this command are set independently in Standard and Page 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.

character orientation changes in 90 degree clockwise-rotation mode, the
relationship between vertical and horizontal directions is reversed.
In Page Mode, vertical and horizontal direction 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

printing a black background. When the White/Black reverse printing 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 mode has a higher priority than Underline Mode. When
Underline Mode is on and White/Black Reverse Print Mode is selected,
Underline Mode is disabled, but not canceled.
Exceptions:
This command is only valid on the receipt station.
This is only available in A758 Native Mode.

Decimal:

Range of n:
0 – 255
Selects a 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

Status Commands
Status Command Introduction
The A758 has three methods of providing status to the application. These
methods are through Batch Status Commands, Real Time Status Commands, and
Auto Status Back. 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 are NOT
stored in the printer’s buffer. Instead, they are acted on immediately (regardless
of the printer’s BUSY status) and their response (if any) is returned to the
application. 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.
Auto Status Back – 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 Auto Status Back) triggered a response from
the printer.

A758 Owner’s Guide
Chapter 7: Programming Guide
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.

PAPER EXHAUST LINE is valid to indicate previously requested status.
This command allows the printer to inform the host when the data in the buffer
has been processed, when the IEEE 1284 interface is in unidirectional mode.
When this command is sent to the printer, the printer goes “Busy” until all data
which has been sent to the printer has been processed. The PAPER EXHAUST
line shows the status for the cash drawer or receipt paper as shown in the table.
Status information is limited to what can be sent by the dedicated lines: BUSY,
ACK, PAPER EXHAUST, and FAULT.

each diagnostic item. Most of the diagnostic items are maintained in non-volatile
memory (NVRAM), but some are maintained in read-only memory (ROM).
The table that follows describes the variables.
The first item group in the table includes an example of data to send and to
receive. Data sent from the host to write to NVRAM must contain all digits
required by the remote diagnostic item. All data must be ASCII. The printer
returns all ASCII data. It is preceded by the parameter n to identify the diagnostic
item and is followed by a Carriage Return (0D) to signify the end of the data.

Value of n:

4, 52 = Flash Memory status
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 RS232C 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 RS232C communications handshaking control is selected, the
printer transmits the one byte response regardless of the host signal DSR.
When Auto Status Back (ASB) is enabled using the Enable/Disable Automatic
Status Back command (1D 61), the status transmitted by this command (Transmit
Status) and the ASB status must be differentiated according to the information
found in Recognizing Data from the Printer. This is found in the Real Time

Chapter 7: Programming Guide
Real Time Commands
These commands provide an application interface to the printer even when the
printer is not handling other commands (RS-232C communication interface only):
♦
Real Time Status Transmission (GS Sequence and DLE Sequence)
♦
Real Time Request to Printer (GS Sequence and DLE 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 are
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, slip paper jam, 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 to correct these
problems. 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 upon receiving it 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.
September 1999
164
A758 Owner’s Guide
Chapter 7: Programming Guide
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.
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
Another consideration is that an application should take care not to 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 out of 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 sequences are being used, the last byte stored when the buffer fills
up could be the DLE code, with no room for the subsequent EOT or ENQ. When
this lone DLE byte is finally processed out of the buffer it will be interpreted as a
Clear Printer command.
Similarly, when the GS sequences are being used, the last byte stored when the
buffer fills up could be the GS code, with no room for the subsequent EOT or
ETX or ENQ. When this lone GS byte is finally processed out of the buffer it will
use the next byte, whatever it is, as the second byte in its GS sequence.
To guard against this situation, an application should determine the cause of a
busy condition and take appropriate action or pace further real time commands
to avoid filling the buffer. There are a minimum of 256 bytes available in the
printer’s buffer when it goes busy.

handled exactly the same as 10 04 n.

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.
If the receipt is selected, 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.
If the slip is selected, this command will attempt recovery from a slip motor or
flip jam by re-homing the printhead and waiting for a slip to be inserted before
restarting the print. Other errors associated with the slip, such as cassette door
open, can be recovered from only by clearing the specific condition, such as
closing the cassette door.
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.
If the slip was selected when the error occurred, the receipt becomes selected
when the buffers are cleared. When printing on the slip is to continue, the slip
must be selected again.
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.

m = 0 – 6, 10
d = 32 - 126 (see the table)
n = 1 - 255 (see the table)
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 barcode 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 to compensate for the Code 128 bar code, which can accept a NUL
character as part of the data. With the second variation the length of byte is
specified at the beginning of the string.
Fixed-length codes can be aligned left, center, or right using the Align Positions
command (1B 61). Variable-length codes are always center aligned in A756
Emulation.
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.

Page Mode Commands
Page Mode is one of two modes, which the A758 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
(0x0C) 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.
Limitations
Page mode is only implemented on the receipt station in A758 Native Mode only.
Print and Return to Standard Mode
ASCII:
FF
Hexadecimal: 0C
Decimal:
12
The processed data is printed and the printer returns to Standard Mode. The
developed data is deleted after being printed. This command has the same code
as the Print and Eject Slip command, which is executed when the printer is not in
Page Mode.
Exceptions:
This command is enabled only in Page Mode.
Cancel Print Data in Page Mode
ASCII:
CAN
Hexadecimal: 18
Decimal:
24
Deletes all the data to be printed in the “page” area. Any data from the
previously selected “page” area that is also part of the current data to be printed
is deleted.
This command has the same code as the Open Form command, which is
performed when the printer is not in Page Mode.
Exceptions:
This command is only used in Page Mode.

Print Data in Page Mode
ASCII:
ESC FF
Hexadecimal: 1B 0C
Decimal:
27 12
Collectively prints all buffered data in the printing area.
After printing, the printer does not clear the buffered data and sets values for
Select Print Direction in Page Mode (1B 54 n) and Set Print Area in Page Mode
(1B 57…), and sets the position for buffering character data.
Exceptions:
This command enabled only in Page Mode.
Select Page Mode
ASCII:
ESC L
Hexadecimal: 1B 4C
Decimal:
27 76
Switches from Standard Mode to Page Mode. After printing has been completed
either by the Print and Return to Standard Mode (FF) command or Select
Standard Mode (1B 53) the printer returns to Standard Mode. The developed
data is deleted after being printed.
This command sets the position where data is buffered to the position specified
by Select Print Direction in Page Mode (1B 54) within the printing area defined
by Set Print Area in Page Mode (1B 57).
This command switches the settings for the following commands (which values
can be set independently in Standard Mode and Page Mode) to those for Page
Mode.
♦
Set Right-Side Character Spacing (1B 20)
♦
Select 1/6-Inch Line Spacing (1B 32)
♦
Set Line Spacing (1B 33)
It is possible only to set values for the following commands in Page Mode. These
commands are not executed.
♦
Select or Cancel 90 Degree Clockwise Rotation (1B 56)
♦
Select Justification (1B 61)
♦
Select or Cancel Upside-Down Printing (1B 7B).
♦
Set Left Margin (1D 4C)
♦
Set Print Area Width (1D 57)
Exceptions:
The command is enabled only when input at the beginning of a line.
The command is available only when the receipt is selected by Select Paper
(1B 63 30).
The command has no effect if Page Mode has previously been selected.
The Select Paper (1B 63 30) command can not be used in Page Mode.
In A756 Emulation Mode, (1B 4C…) is used for double density graphics.

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 by the Eject Slip command (0C).
Defaults equal an origin of 0,0 and a size of 576x576. This command is allowed in
any mode.
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.
See the illustration for a graphic representation of the printing area. For more
information about the fundamental calculation pitch, see the Set Fundamental
Calculation Pitch command (1D 50).
♦
x0 = [(n1 + n2 x 256) x (horizontal direction of the fundamental calculation
pitch)]
♦
y0 = [(n3 + n4 x 256) x (vertical direction of the fundamental calculation
pitch)]
♦
dx = [(n5 + n6 x 256) x (horizontal direction of the fundamental calculation
pitch)]
♦
dy = [(n7 + n8 x 256) x (vertical direction of the fundamental calculation
pitch)]
Keep the following notes in mind for this command.
♦
The fundamental calculation pitch depends on the vertical or horizontal
direction.
♦
The maximum printable area in the x direction is 576/203 inches.
♦
The maximum printable area in the y direction is 2000/203 inches.

Set Absolute Vertical Print Position in Page Mode
ASCII:
GS $ nL nH
Hexadecimal: 1D 24 nL nH
Decimal:
29 36 nL nH
Formulas:
[(nL + nH X 256) x (vertical or horizontal motion unit)] inches.
Sets the absolute vertical print starting position for buffer character data in
Page Mode.
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 direction 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.
Exceptions:
This command is effective only in Page Mode.
If the [(nL + nH x 256) x (vertical or horizontal motion unit)] exceeds the specified
printing area, this command is ignored.

Set Relative Vertical Print Position in Page Mode
ASCII:
GS \ nL nH
Hexadecimal: 1D 5C nL nH
Decimal:
29 92 nL nH
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.
This command functions as follows, depending on the print starting position set
by Select Print Direction in Page Mode (1B 54):
1.
When the starting position is set to the upper left or lower left of the printing
area, the vertical motion unit (y) is used.
2.
When the starting position is set to the upper right or lower left of the
printing area, the horizontal motion unit (x) is used.
Value:
The value for the horizontal and vertical movement cannot be less than the
minimum horizontal movement amount, and must be in even units of the
minimum horizontal movement amount.
Formulas:
The distance from the current position is set to [(nL + nH x 256) x vertical or
horizontal motion unit] inches. The amount of movement is calculated only for
the receipt.
When pitch n is specified to the movement downward:
nL + nH x 256 = n
When pitch n is specified to the movement upward (the negative direction), use
the complement of 65536.
When pitch n is specified to the movement upward:
nL + nH x 256 – 65536 – N
Exceptions:
This command is used only in Page Mode, otherwise it is ignored.
Any setting that exceeds the specified printing area is ignored.

Macro Commands
These commands are used to select and perform a user-defined sequence of
printer operations.
Start or End Macro Definition
ASCII:
GS :
Hexadecimal: 1D 3A
Decimal:
29 58
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.
Exceptions:
If the macro definition exceeds 2048 bytes, excess data is not stored.
This command is available in A758 Native Mode only.

Value of r:
Value of t:
The number of times to execute the macro.
The waiting time for executing the macro.
Executes a macro. After waiting for a specified period the LED indicators blink
and 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 x 100 msec 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.
This command is available in A758 Native Mode only.

Ten parameters are more than enough to specify all variable length fields with a
field separator each and other status information that may be helpful to an
application. More than 10 parameters are not recommended because they use up
space in non-volatile memory (NVRAM) available for the exception table.
The parsing parameter string is stored packed in NVRAM starting at word 10,
with the total byte length stored in the high order byte of word 10. While most
parameters take two bytes of NVRAM, the following parameters take only one
byte: B, D, E, S, L. None of the parsing examples in the following section take
more than 14 bytes (seven words) of NVRAM.
The exception table starts at word 20. If the parsing parameter string extends into
word 20, then the first exception table entry is unavailable.

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. This is the default parsing format if no other is selected:
Status

Bad read, data follows
0x01
No check present, no data

Check Serial Number
Parsing the Check Serial Number
Most banks print the check serial number in three easily recognizable spots. The
printer firmware will look for the number in these spots, using the following
ordered algorithm. The examples use letters to represent symbols on the check:
t
Transit symbol
o
“on us” symbol
$
Amount symbol
-
Dash
c
Check serial number
x
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.
September 1999
193
A758 Owner’s Guide
Chapter 7: Programming Guide
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 with a sumcheck written in the last word. 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.
September 1999

A758 Owner’s Guide
Chapter 7: Programming Guide
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.

To load the second table entry, which starts at word 25, the transit number
123456780 would be stored in the first two words of its table entry using this
string of commands:
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)
then stored in the other three words of the table entry using:

commands:
0x1B 0x73 0x22 0x13 30
0x1B 0x73 0x76 0x32 31
After the right transit symbol are four characters to skip, a seven digit account
number, two characters to skip, and finally a four digit check serial #. The final
character to skip need not be encoded. These would be bitwise encoded as:
100
010

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

Loads user-defined characters to Flash Memory. An application must use this
command to store user-defined characters in Flash Memory. Any user-defined
characters defined following this command are stored in Flash Memory. A userdefined character cannot be redefined in Flash Memory. The Flash Memory page
must be erased by an application before redefining user-defined characters. For

n1 is the number of 64k sectors used for logos and user-defined characters.
n2 is the number of 64k sectors used for user data storage.
This command sets the allocation of Flash sectors between user data storage and

Value of n:
49 - 50
Erases a page of Flash Memory and sends a carriage return when the operation is
complete.
n = 49 (ASCII n = 1)
This command erases all sectors available for user-defined characters and
multiple logos. The page should be erased in two situations: when the logo
definition area is full and an application is attempting to define new logos, and
when an application wants to replace one user-defined character set with
another. In both cases, all logos and character set definitions are erased and must
be redefined.
n = 50 (ASCII n = 2)
This command erases all sectors available for user data storage.
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. 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 five seconds after sending
the Erase User Flash Sector (1D 40 n) command before sending data.

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, use the command Switch to Flash
Download Mode, 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.
