Chapter 1: About the 7193 Printer
The 7193 thermal receipt printer is fast (at 1020 lines per minute), quiet, and very reliable.
With thermal printing technology, there is no ribbon cassette to change, and paper loading
is extremely simple. The printer is small enough to fit almost anywhere and is easy to use
with the receipt exiting from the top. There is no journal as it is kept electronically by the
host computer.
Models
There are several models of the 7193 depending on the communication interface and the
combination of options selected.
Communication Interfaces
•
RS-232C
•
Parallel
See “Chapter 5: Communication” for more information about the communication

Thermal Printhead
The 7193 uses a thermal printhead for printing receipts, and it is extremely fast and quiet.
Since it uses heat to print directly on paper, there is no cassette or ribbon to change,
eliminating soiled fingers and paper dust.
The printhead is designed for a very long life, but it may be replaced if needed. Only a
trained service technician may replace the printhead. See “Chapter 3: Solving Problems” to
determine if the printhead needs to be replaced. If the printhead needs to be replaced,
contact your Axiohm-authorized service organization. See “Cleaning the Printer” later in
this chapter for cleaning instructions for the printhead.

Cleaning the Printer
There is no customer maintenance required for the 7193.
Cleaning the Cabinet
Clean the cabinet as needed to remove dust and finger marks. Use any household cleaner
made for plastics, but test it first on a small unseen area. If the receipt paper bucket is dirty,
wipe it with a clean, damp cloth. The cabinet materials and finish are durable and are
resistant to the following items:
•
Cleaning solutions
•
Lubricants
•
Fuels
•
Cooking oils
•
Ultraviolet light
Cleaning the Thermal Printhead
If the printhead appears dirty, clean it with cotton swabs and rubbing alcohol.
Caution: Do not spray the thermal printhead with household cleaner as this may damage
it and the electronics.
If spotty or light printing problems persist after cleaning the thermal printhead, contact
your NCR authorized service representative.
Note: The thermal printhead does not normally require cleaning if the recommended
paper grades are used. If non-recommended paper has been used for an extended period
of time, cleaning the printhead with the alcohol pen will not be of much benefit. See
“Ordering Thermal Paper” earlier in this chapter for recommended paper.

Be prepared to answer questions concerning shipping and billing.
Choosing a Location
The 7193 is compact and requires little counter space. It may even be mounted on a wall if
space is at a premium. See “Mounting the Printer on a Wall” later in this chapter. The
power supply may also be mounted on a wall or under a table. See “Mounting the Power
Supply on a Wall” later in this chapter. Be sure to plan for the length of the communication
and power cables when choosing a location.
Make sure there is enough room to open the receipt cover and change the paper. The
following illustration shows the actual dimensions of the printer, but leave several inches
around the printer for connecting and accessing the cables.
Setting Switches
A group of switches, called DIP switches, located on the bottom of the 7193, is used for the
following purposes:
6
•
To set variables for several printer functions (see the sections for the various printer
functions in “Level 1 Diagnostics” in chapter 4)
•
To set communication parameters for the RS-232C interface or the Parallel interface
(see “RS-232C Switch Settings” or “Parallel Switch Settings” in chapter 5)
•
To perform diagnostic tests (see the sections for the various diagnostic tests in “Level 1
Diagnostics” in chapter 4)
August 1998
7193 Owner’s Guide
Chapter 2: Setting Up the Printer
•
To set the data buffer for the Parallel communication interface (see “Parallel Switch
Settings” in chapter 5)
Caution: The DIP switches are set at the factory to predetermined settings and should
generally not be changed. If you must change the settings do so carefully to avoid
changing other functions.
Before changing any of the switches, first run the print test to print out the current switch
settings on the receipt. See “Testing the Printer” later in this chapter for instructions on
running the print test and for a sample printout.
Note: Switch #1 is used to toggle between communication with the host computer and the
setup mode (used for the printer functions and level 1 diagnostic tests):
•
Switch #1 OFF: printer is on-line, able to communicate with the host computer
•
Switch #1 ON: printer is in Level 1 Diagnostics (setup mode)
If you want the printer to communicate with the host computer, be sure switch 1 is OFF.
Use a paper clip or other pointed object to set the switch.
For additional information on the setup mode (Level 1 Diagnostics), see chapter 4.
Note: Some 7193 models may appear slightly different than what is shown in the
illustration. The procedures are the same for all models unless otherwise noted.

Connecting Cash Drawer Cables
The cash drawer option allows up to two cash drawers to be connected to the printer in a
system with a host computer that has no connectors for the cash drawer cables. The cash
drawer cables usually come with the cash drawer.
The cash drawers are operated by software command from the host computer through the
printer. For additional information on the printer commands used by the host computer to
activate the cash drawers, see “Chapter 6: Commands.”
1.
Plug the cash drawer cables into the connectors on the printer.
The connectors are standard phone connectors.
2.
If only one cash drawer is used, plug the cable into the connector labeled 1.
Note: Some 7193 models may appear slightly different than what is shown in the
illustration. The procedures are the same for all models unless otherwise noted.

Loading and Changing Paper
The 7193 features extremely simple paper loading. See the next two illustrations.
If you are loading paper for the first time and have already taken the roll out, go to
“Putting In the Paper Roll” later in this chapter. If you have not taken the roll out, continue
with the following instructions. Although the illustrations show a used roll being removed,
the instructions still apply to loading paper for the first time.
When to Change the Paper
Change the paper when either of the following two conditions occurs:
•
Paper low stripe appears on the receipt paper
Change the paper as soon as possible to avoid running out of paper part way through
a transaction.
•
Paper Out light (red) turns on
Change the paper immediately or data may be lost.
Caution: Do not operate the printer or host computer if the printer runs out of paper. The
printer will not operate without paper, but it may continue to accept data from the host
computer. Because the printer cannot print any transactions, the data may be lost.

Testing the Printer
Run this test to check the printer. The test prints the settings for several functions, prints all
variations of the character sets, and partially cuts the paper between each variation. See
“Level 1 Diagnostics” in chapter 4 for a description of the functions.
A sample printout of RS-232C printers is shown on the facing page. The printouts for other
models are similar. The test ends with a partial cut, then begins again. Several feet of paper
can be used to print one pass of the test.
Additional diagnostic tests may be performed by a trained service representative. For more
information, see “Chapter 4: Diagnostics.”
Note: The operator panel may differ from the standard version (shown on top in the
illustration on the facing page) depending on the model. On models matching the alternate
version (shown on bottom in the illustration), use a paper clip or pointed object to press the
plunger to put the printer on- or off-line.
1.
Press the On Line Button (or plunger) on the operator panel to put the printer off-line.
The On Line light turns off indicating the printer is off-line.
2.
Press and hold the Paper Feed button while pressing the On Line Button (or plunger).
3.
Let go of the Paper Feed button once the printing begins.
The printer begins printing the data and character sets until you stop the test. This can
be given to a service representative if it appears there is a problem.
4.
To stop the test, press the Paper Feed button.

Mounting the Printer on a Wall
Use the wall-mount kit to mount the printer vertically on a wall. See “Ordering Other
Supplies” in chapter 1 for information on ordering the printer wall-mount kit.
The kit contains a mounting bracket, screws with plastic anchors, and a label. Once the
printer is mounted on the wall, the operator panel will be upside down. The label corrects
this so the panel can be easily read.
Select a wall that is accessible, but away from main traffic to keep the printer from being
bumped or knocked off. Be sure there are no hidden wires or other obstructions in the wall
where you mount the printer. Keep in mind the length of the cables when mounting the
printer on the wall.
You will need a 1/4 inch drill bit (approximately 6 mm) and either a Phillips or standard
screwdriver (screws are combination Phillips and pan-slotted).
1.
Using the bracket as a template, mark and drill a hole for each plastic anchor 32 mm
(1.25 inches) deep.
2.
Insert the anchors into the holes so they are flush with the wall surface and screw the
bracket against the wall, tightening the screws so that the plastic anchors expand and
hold firmly in the wall.
Do not overly tighten the screws.
Note: Because the power cable and communication cable connect to the bottom of the
printer, they must be connected before the printer can be attached to the bracket. If you
haven't connected the cables to the printer, do so now. See “Connecting Communication
and Power Cables” earlier in this chapter.
3.
Line up the tabs of the bracket with the slots on the back of the printer and attach the
printer to the bracket.
4.
Place the label on the cover.

Mounting the Power Supply on a Wall
The power supply can be ordered with a wall-mount kit to mount the power supply on the
wall or under a table. See “Ordering Other Supplies” in chapter 1 for information on
ordering the power supply with or without a wall-mount kit.
The kit contains a holder and screws with plastic anchors. Be sure there are no hidden
wires or other obstructions in the wall where you mount the power supply.
You will need a 1/4 inch drill bit (approximately 6 mm) and either a Phillips or standard
screwdriver (screws are combination Phillips and pan-slotted).
1.
Using the bracket as a template, mark and drill a hole for each plastic anchor 32 mm
(1.25 inches) deep.
2.
Insert the anchors into the holes so they are flush with the wall surface and screw the
holder against the wall, tightening the screws so that the plastic anchors expand and
hold firmly in the wall.
Do not overly tighten the screws.
Note: You must unplug the power cord in order to place the power supply in the holder.
First, take the printer off-line by pressing the On Line button on the operator panel (the On
Line light goes off indicating the printer is off-line), unplug the power cord from the outlet,
then unplug the power cord from the power supply.
3.
Place the power supply in the holder.
4.
Plug the power cord into the power supply.
5.
Plug the power cord into an outlet.
Note: You can use the tie-wrap to wrap the power supply cable to keep it out of the way.

Chapter 3: Solving Problems
Chapter 3: Solving Problems
The 7193 printer is a simple, generally trouble-free printer, but from time to time minor
problems may occur. For example, the power supply may be interrupted or the printhead
may overheat for some reason.
Lights on the operator panel will signal that something may not be operating properly: one
green light and one red light may either flash or glow continuously as described in the
following table and on the following pages.

Correcting Problems
Operator-Correctable Conditions
The following conditions can be corrected generally without calling for service. However,
if problems persist, contact your NCR authorized service representative to arrange for a
service call.
Paper Out
Replace the paper roll. Do not operate the printer or host computer if the printer runs out
of paper. The printer will not operate without paper, but it may continue to accept data
from the host computer. Because the printer cannot print any transactions, the data may be
lost.
See “Loading and Changing Paper” in chapter 2 for more information.
Knife Failure or Paper Jam
A problem or jam has occurred with the knife. Open the receipt cover and visually inspect
the knife inside the cover. Clear any jammed paper you can see. Tear off any excess paper
against the tear off blade.
Contact your NCR authorized service representative if this does not resolve the problem.
Receipt Cover Open
Check that the receipt cover is completely closed. You can tell if it is not closed properly if
it swings open easily. When closed properly, it requires some exertion to open because of
the snug fit.
Service-Related Problems
The following problems may require you to contact your NCR authorized service
representative to correct the problem.
Print Head Over/Under Temperature
There is a problem with the temperature of the printhead. It must remain within a certain
temperature range to operate properly. This problem will most often occur when the
printhead overheats rather than running under temperature.
The printhead may overheat when printing in a room where the temperature is above the
recommended operating temperature or when printing high density graphics
continuously. In either case, the printer will shut off. See “Appendix A: Specifications” for
information on the recommended temperature range for operating the printer and on the
restrictions of printing high density graphics continuously.
If the operating temperature is too hot, adjust the room temperature or move the printer to
a cooler location. If the printhead is overheating because of printing graphics continuously,
reduce the demand on the printer.
If the printer continues to overheat, contact your NCR authorized service representative.

Chapter 3: Solving Problems
No Power to Printer or Power Voltages Incorrect
The power being supplied to the printer is not in the normal range. Check that all
connections are correct. Make sure the power supply is plugged in and that the printer is
on-line.
Contact your NCR authorized service representative if this does not resolve the problem.
Print is Light or Spotty
The printhead may be dirty. Clean it with cotton swabs and rubbing alcohol.
Caution: Do not spray the thermal printhead with household cleaner as this may damage
it and the electronics.
If spotty or light printing problems persist after cleaning the thermal printhead, contact
your NCR authorized service representative.
Note: The thermal printhead does not normally require cleaning if the recommended
paper grades are used. If non-recommended paper has been used for an extended period
of time, cleaning the printhead with alcohol will not be of much benefit. See “Ordering
Thermal Paper” in chapter 1 for recommended paper.
Contacting a Service Representative
For serious problems, such as the ones mentioned in the previous section, contact your
NCR authorized service representative to arrange for a service call.

Chapter 4: Diagnostics
The following diagnostic tests are available for the 7193:
•
Level 0 Diagnostics
Performed during the startup cycle
•
Level 1 Diagnostics (setup mode)
Available in a dedicated environment and accessed through the DIP Switches
•
Level 2 Diagnostics
Performed during normal printer operation
•
Level 3 Diagnostics
Maintained during normal operation and printed in the print test
Level 0 Diagnostics
The printer automatically performs level 0 diagnostics during the startup cycle when
power is supplied or when the printer is put on-line. Level 0 diagnostics comprise the
following actions:
•
Motors are turned off
•
Microprocessor timing is checked, CRC check of the firmware ROM is performed,
external RAM is read
Failure causes level 0 diagnostics to stop; the printer beeps once when the test is
successfully completed.
•
Checks if paper is present
•
Homes knife
Failure causes a fault condition.
•
Checks if receipt cover is closed
Failure does not interrupt the startup cycle.
When the last step is complete, the Paper Feed button is enabled and the printer is ready
for normal operation. Information about the test is available to the communication
interface through the commands.
If the printer has not been turned on before, or a new EEROM has been installed, the
default values for the printer functions (set in Level 1 Diagnostics) will be loaded into the
EEROM during level 0 diagnostics. The printer beeps twice when this occurs. See the tables
in “Level 1 Diagnostics” for the printer settings. If the printer beeps twice at any other
time, it indicates that the EEROM has failed.

Level 1 Diagnostics
Level 1 Diagnostics (setup mode) allow you to change settings for various printer functions
(described on the following pages) and to run certain tests using the DIP switches.
Keep the following information in mind when changing the settings:
•
Turn the printer off by pressing the On Line button (or plunger). Although the printer
still receives power, this is sufficient for changing the DIP switches.
•
The settings can only be changed when the printer is in level 1 diagnostics (setup
mode): switch 1 must be set to On.
•
Turn the printer back on. The printer beeps, and the On Line light (green) blinks.
•
Once the settings have been changed and stored in the EEROM, the DIP switches must
be set back to the on-line settings for the printer to operate.
•
The stored settings for the functions are printed with a dump of all resident characters
during a print test. See “Testing the Printer” in chapter 2.
•
The default settings are set at the factory and are stored in the history EEROM.
Caution: If you change the switch settings, be sure they are correct for that particular
function or test to avoid changing the settings for another function or test. If the settings
are accidentally changed, see the tables in this section to change the settings back. If you
need assistance, contact your NCR-authorized service representative.
The functions and tests are described in the following order in this section:
•
Setting Data Error (RS-232C only) and Data Buffer options
•
Setting printhead resistance
•
Setting default lines per inch
•
Setting partial cut distance
•
Ignoring/using the carriage return
•
Running the data scope mode
Setting Data Error and Data Buffer options
This function allows you to select the handling of data reception errors (RS-232C only) and
to select the size of the data buffer.
Note: The operator panel may differ depending on the model. To turn the printer on or
off, (on-line or off-line), use a paper clip or other pointed object to depress the plunger (in
place of the On Line button) on models with that item.
Caution: The DIP switches are pre-set at the factory and should generally not be changed.
If you must change them, do so carefully to avoid changing other functions. Run the print
test to see the current settings for this function. See “Testing The Printer” in chapter 2.

Level 2 Diagnostics
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:
•
Paper out, cover off, or knife unable to home
•
Printhead too hot or voltages out of range
The lights on the operator panel will signal when these conditions occur as well as indicate
what state or mode the printer is in. See “Chapter 3: Solving Problems” for a table
describing the operator panel lights and for general troubleshooting information.

Chapter 5: Communication
Chapter 5: Communication
Communication Overview
In order for a receipt to be printed, a program must be in place that translates the data
from the host computer into a language that the printer can understand. This program
must tell the printer exactly how to print each character. This chapter describes how to
create such a program or modify an existing one.
Interfaces
In order for the printer to communicate with the host, a communication link must be set
up. The 7193 supports the following communication interfaces:
•
RS-232C Interface
•
Parallel Interface
Each of these has a protocol associated with it that the host must understand and adhere to.
Only when the interface parameters are matched and the proper protocol is used will the
host and the printer be able to communicate. See the respective sections in this chapter for
a description of the protocol associated with each type of interface.
Sending Commands
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, 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 any print
command to the proper port, commands can be sent from any software program.
August 1998
33
Chapter 5: Communication
7193 Owner’s Guide
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$(&H0A)
sends the hexadecimal number 0A to the printer, which causes the printer to print the
contents of its print buffer. Previously sent commands tell the printer exactly how this data
should appear on the paper. For example,
LPRINT CHR$(&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 outputs to must be
matched to that of the printer.
RS-232C Interface
The RS-232C interface uses either XON/XOFF or DTR/DSR protocol. 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 coordinate the
information flow.
The RS-232C version of the 7193 offers the standard options which are selected with the
DIP switches. See “RS-232C Switch Settings” later in this chapter for the switch settings.
Print Speed and Timing
The faster speed of new 7193 models requires the application to send data to the printer at
least as fast as it is printed. The application must also allow receipt 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 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 1020 lines/minute.
The table shows that with a pause of 50 milliseconds after each line, the transmit time
equals or exceeds the print time, slowing down the printer, regardless of the baud rate.

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.
XON character = hexadecimal 11.
XOFF character = hexadecimal 13.
DTR/DSR Protocol
The DTR signal is used to control data transmission to the printer. It is driven low when
the printer is ready to recieve 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.

RS-232C Switch Settings
The DIP switches are located on the printed circuit board and are accessed from the bottom
of the printer. You do not need to remove any covers to change the DIP switches.
The DIP switches are used to set the RS-232C parameters and the Data Error and Data
Buffer options as shown. These parameters must match those of the host computer in order
for the host computer and the printer to communicate.
Caution: The switches can also be used for setting other functions and tests. Be careful
when setting the switches for the RS-232C settings that you do not accidentally change the
settings for the other functions and tests. See “Level 1 Diagnostics” in chapter 4 for more
information.
Use a paper clip or other pointed object to set the switches.
Note: The operator panel may differ depending on the model. To turn the printer on or
off, (on-line or off-line), use a paper clip or other pointed object to depress the plunger (in
place of the On Line button) on models with that item.
1.
Press the On Line button (or plunger) to put the printer off-line.
2.
Turn the printer over and set the switches to the desired settings shown in the table.
Switch 1 must be set to Off when setting switches for the RS-232C settings. This puts
the printer in the on-line mode to communicate with the host computer.
Caution: Do not set DIP switch 1 to On. Setting switch 1 to On puts the printer in level 1
diagnostics (setup) mode where other functions and tests can be changed.

Chapter 6: Commands
Chapter 6: Commands
The commands control all operations and functions of the 7193 printer, from selecting the
size and placement of characters and graphics on the receipt to feeding and cutting the
paper.
Note: All versions of the 7193 use the same commands as listed in this section unless
otherwise noted. For example, the Parallel interface requires unique commands for
controlling the cash drawer.
The 7193 commands emulate two printers: the NCR 7150™ Multifunction printer and the
Epson TM-T80™ Thermal printer. Any of the commands from either set may be used in
any combination to program a host computer to communicate with the 7193 (unless
otherwise noted).
Some commands listed and described here are not implemented in the 7193 (they are
identified as not implemented). If received, they are ignored and not sent to the print
buffer as data. Non-legal commands are sent to the print buffer as data.
Command List
This section groups the commands according to the following categories:
•
Printer Function Commands
•
Print Characteristics Commands
•
Graphics Commands
•
Printer Status Commands
•
Real Time Commands
•
Bar Code Commands
Within each group, the commands are listed in numerical order of their hexadecimal
codes. The page number refers to where a complete description of each command is given

When x or y is set to 0, the default setting for that motion unit is used.
Notes
The default horizontal motion is x = 150. Before this command was implemented on the
7193, the default horizontal motion unit was also x = 150, except for graphics. The default
for graphics was x = 1/300 inch when using the Set Absolute Starting Postion command
(1B 24) and Set Relative Starting Position command (1B 5C). The purpose of this was to
emulate the Epson LQ-950.
These two commands remain unchanged for existing applications, but their operation is
affected if the Set Horizontal and Vertical Minimum Motion Units command is used.
Likewise, before this command was implemented, the default vertical motion unit was y =
360, to emulate the Epson TM-T80. That emulation was used for the Set Line Spacing to n
Minimum Units command (1B 33) and Print and Feed n Minimum Units command (1B
4A). These two commands remain unchanged for existing applications, but their operation
is affected if the Set Horizontal and Vertical Minimum Motion Units command is used.
Select Cut Mode and Cut Paper

Graphics Commands
These commands are used to enter and print graphics data and are described in order of
their hexadecimal codes:
Set Absolute Starting Position
Sets the print starting position for graphics at the specified number of dots from the
beginning of the line as expressed in the following formula: n = ((n1 + (256 x n2)) x 2). The
resulting dot column must be less than 448. The print starting position is reset to column
one after each line.
This command emulates the Epson LQ-950™ dot matrix printer. This allows the 7193 to
accept graphics that are normally output from word processing programs to a half-dot
matrix printer.

Chapter 6: Commands
7193 Owner’s Guide
Printer Status Commands
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 were received.
When a fault occurs, the printer will go busy at the RS-232C interface and not respond to
either of the 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.
Printers manufactured after mid 1996 include Real Time commands which are handled
when the printer is busy at the RS-232C interface. See the following section, “Real Time
Commands,” for details about these commands.
Transmit Cash Drawer Status
Transmits current status of the cash drawers. One byte is sent to the host computer. This
command is available only on RS-232C printers.
In DTR/DSR protocol the printer waits for DSR = SPACE. If a drawer is not connected, the
status will indicate closed.

This command is a batch mode command; that is, the response is transmitted 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.
Notes
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 Printer ID) and the
ASB status must be differentiated according to the information found in “Recognizing Data
from the Printer,” (in the “Real Time Commands” section later in this chapter).

selected, ASB is disabled. All four status bytes are transmitted without checking DSR.
If the error status is enabled, a change in the following conditions will trigger the ASB:
•
Receipt Cover
•
Knife Error
•
Out-of-Range Printhead Temperature
•
Out-of-Range Voltage
•
Paper Exhaust
When the printer is disabled by the Select Peripheral Device command (1B 3D), this
command (Enable/Disable Automatic Status Back) is disabled but Automatic Status Back
is not disabled.
When Auto Status Back (ASB) is enabled using this command, the status transmitted by
other commands and the ASB status be differentiated according to the information found
in “Recognizing Data from the Printer,” (in the “Real Time Commands” section later in this
chapter). The status bytes to be transmitted are described in the following four tables.

Transmit Status
Transmits the status specified by n.
This command is a batch mode command; that is, the response is transmitted after all prior

Notes
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

Real Time Commands
The Real Time 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 (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 original Printer Status commands, Transmit Printer Status (Hex 1B 76, ASCII ESC v)
and Transmit Cash Drawer Status (Hex 1B 75 0, ASCII ESC u 0) 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 which 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 other error.
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.
First Implementation
For a new application the GS (Hex 1D) sequences of the first implementation are
recommended to avoid possible misinterpretation of a DLE (Hex 10) sequence as a Clear
Printer (Hex 10 0, ASCII DLE NUL) command.
The first implementation builds upon the GS ENQ sequence as implemented on Epson’s
TM-930II™, TM-950™ and TM-U950™ by defining two new GS (Hex 1D) sequences to
provide the same functions as the DLE (Hex 10) sequences above, and to provide complete
backward compatibility to the original 7193 Clear Printer command.
An application using these GS (Hex 1D) sequences does not need to distinguish for the
printer between the new Real Time commands and the old Clear Printer command. This
implementation is ideal for an existing 7193 application which already uses the Clear
Printer command or for a new application being developed.
This implementation also provides the original GS ENQ Real Time sequence in addition to
the newer Real Time sequences.
70
August 1998
7193 Owner’s Guide
Chapter 6: Commands
Alternate Implementation
The alternate implementation uses the DLE (Hex 10) sequences as implemented on Epson’s
TM-T85™ and TM-U950™. An application using these DLE (Hex 10) sequences and the
original 7193 Clear Printer command must distinguish for the printer between the new
Real Time commands and the old Clear Printer command by adding a NUL (Hex 00) to the
Clear Printer command.
An application using these DLE (Hex 10) 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. This implementation is useful for an existing TM-T85™ or TMU950™ application which is being migrated to a 7193. This application would not be using
the 7193 Clear Printer command at all since it is not recognized by the Epson printers.
Note: The DLE (Hex 10) sequences as implemented on Epson’s TM-T85™ and TM-U950™
are not exactly the same as those implemented on Epson’s TM-950™.
This implementation also provides the original GS ENQ Real Time sequence in addition to
the newer Real Time sequences.
Rules for Using Real Time Commands
Three situations must be understood when using Real Time commands.
1.
First, the printer executes the Real Time command upon receiving it and will transmit
status regardless of the condition of the DSR signal.
2.
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.
3.
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 GS ENQ or GS EOT 1 or DLE EOT 1. The reason for a
particular busy condition can be determined by other responses to GS EOT n or DLE
EOT 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.
August 1998
71
Chapter 6: Commands
7193 Owner’s Guide
When the printer is busy due to an error condition, then data stops being processed 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, 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 are a minimum of 256 bytes available in the printer’s buffer when it goes
busy.
Busy Line and Fault Conditions
An additional improvement is made in the way the 7193 RS-232C handles the busy line (or
busy condition when using XON/XOFF) during a fault condition.
Before this improvement, the printer would go busy at the RS-232C interface when the
receipt door was opened or the paper was exhausted as soon as it received the next input
byte. Bytes would continue to be accepted until the buffer was full or the condition was
cleared, but would stop processing data out of the receive buffer. This resulted in the
printer being unable to respond to the batch mode status commands (ESC v and ESC u), or
handle the cash drawer commands even when it was not printing.
The improvement overcomes this limitation by not going busy at the RS-232C interface
until it attempts to process a command out of the receive buffer which it can't do: for
example, print on the receipt when it's out of paper. It will stay busy and stop processing
data out of the receive buffer until the condition clears.
Now if the cover is open or the paper is exhausted, the 7193 printer will still accept data,
respond to the batch mode status commands (ESC v and ESC u), 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.
The only potential backward compatibility issue is if some application expects the 7193 to
go busy when it processes a batch mode status command, which it now won't. To handle
this case, there is now a parameter setup in NVRAM to have the printer handle the busy
line the old way. The default will be the new way, but the printer can be programmed in
the field if it proves to be a problem.
To program the printer to handle the busy line the old way do the following steps:
72
1.
Record the current switch settings for their RS-232C parameters.
2.
Set switches 2 and 3 to OFF, and set switches 1, 4, 5, and 6 to ON.
3.
Power cycle the printer.
4.
Wait until the printer beeps to store the parameter change in NVRAM.
5.
Restore the switches to their RS-232C parameters.
6.
Power cycle the printer.
7.
Print out the diagnostics to be sure that the busy line parameter changed.

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.
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.

Recognizing Data from the Printer
An application sending various Real Time and non-Real Time commands to which the
printer responds can determine which command a response belongs to by the following
table. Responses to ESC u and ESC v are non-Real Time responses and will arrive in the
order in which they were solicited.
Although the original intent of the response to ESC v was to provide error information in
its one-byte response, the response up to now has always been Hex 00 when transmitted.
This is because ESC v was not processed until the error condition was cleared. With the
improvement to the busy line handling described earlier in this section, ESC v will be
processed as long as there is no paper out or cover open error condition.

command is only valid at the beginning of a line. If the width of the bar code exceeds one
line, the excess data is not printed. Illegal data cancels the command.
There are two variations to this command: the first uses a NULL 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 NULL character as part of the data.
Note: Fixed-length codes can be aligned left, center, or right using the Align Positions
(1B 61) command. Variable-length codes are always center aligned.
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.

The value of m selects the bar code system as described in the table. When data is present
in the print buffer, the printer processes the data following m as normal data.
The variable d indicates the character code to be encoded into the specified bar code
system. See the table. If character code d cannot be encoded, the printer prints the bar code
data processed so far, and the following data is treated as normal data.

Print Zones
The printer centers characters (standard pitch and compressed pitch) and graphics on an
80 mm wide (3.15 in.) receipt.
•
Standard pitch: 10 x 18 dots in character cell, 44 characters (columns) per line
•
Compressed pitch: 8 x 18 dots in character cell, 56 characters (columns) per line
•
Graphics: 448 addressable bits
The minimum print line height is 18 dots for characters and 24 dots for graphics. The
standard print line height is 20 dots (3.33 mm, .131 in.) for characters (with two extra dot
rows).
Paper Width = 80 mm (3.15 in.)
Top Margin, 18 mm (.71 in.) Minimum

7193 Owner’s Guide
Density of Receipt Print Lines
When the 7193 prints high density print lines (text or graphics), it automatically slows
down to a rate slower than 1020 lines per minute. High density print lines are defined as
lines with over 57% of the dots printing on the line (there are 448 total dot columns on the
print station).
Duty Cycle Restrictions (Printing Solid Blocks)
There are restrictions on the duty cycle because of the heat generated by the receipt
thermal printhead when printing solid blocks (regardless of the length of the block in
relation to the print line). The restrictions are ambient temperature, the percentage of time
(measured against one minute) of continuous solid printing, and the amount of coverage.
Caution: When the duty cycle approches the limits shown in the table, the receipt
printhead will heat up and shut down. This may damage the printhead.
To avoid this problem, do one or a combination of the following:
84
1.
Reduce the amount of coverage.
2.
Reduce the time of continuous solid printing.
3.
Reduce the ambient temperature.
