Printer Status and Indicators
The TH320/TH420 printers perform a number of diagnostics that provide useful information about the
operating status of the printers. The following diagnostic tests are available.
Startup diagnostics
Performed during the printer’s startup cycle.
Runtime diagnostics
Performed during normal printer operation.
Remote diagnostics
Maintained during normal operation and reported in the print test.
The printer can be configured with the following settings and functions through the configuration
menu that is printed on thereceipt. For more information on configuring the printer, see TH320 and
TH420 User Guides“Printer configuration”.
Communication interfaces Diagnostic modes
RS-232c settings
Printer emulations/software options
Hardware options
Startup diagnostics
When the printer receives power or performs a hardware reset, it automatically performs the startup
diagnostics (also known as level 0 diagnostics) during the startup cycle. The following diagnostics are
performed:
Turn off motors and solenoids.
Perform boot CRC check of the firmware ROM, test external SRAM, test EEPROM, and test main
program CRC. Failure causes Startup Diagnostics to stop; the printer beeps and the light flashes a
set number of times, indicating the nature of the failure. The table in the “Indicators” section (page
16) describes the specific tone and light sequences.
Check if paper is present.
Return the knife to the home position.
Failure causes a fault condition. The table in the “Indicators” section (page 16) describes the specific
tone and light sequences.
Check if receipt cover is closed
Failure does not interrupt the startup cycle.
When the startup diagnostics are complete, the printer makes a two-tone beep (low then high
frequency), the paper feed button is enabled, and the printer is ready for normal operation.
If the printer has not been turned on before, or a new EEPROM has been installed, the default values
for the printer functions will be loaded into the EEPROM during startup diagnostics.
Runtime Diagnostics
Runtime diagnostics (sometimes called level 2 diagnostics) run during normal printer operation. When the
following conditions occur, the printer automatically turns off the appropriate motors and disables
printing to prevent damage to the printer:
Paper out
Receipt cover open
Knife unable to home
Print head too hot
Voltages out of range
The light on the operator panel will signal when these conditions occur as well as indicate what state or
mode the printer is in.

Programmers Guide TH320/420
2
Remote Diagnostics
Remote diagnostics (sometimes called level 3 diagnostics) keeps track of the following tallies and
prints them on the receipt during the print test. See the sample test printout on the next page. These
tallies can be used to determine the printer’s state of health.
Model number
Serial number
CRC number
Number of lines printed
Number of knife cuts
Number of hours the printer has been on
Number of flash cycles
Number of cutter jams
Number of times the cover is opened
Maximum temperature reached
Paper type can be changed in the
configuration menu.
Paper types and grades available:
Type 0 - Monochrome grades
WN T 55
Type 1 - Two-color grades
Kanzaki P-310 RB
Type 4 - Two-color grades
Kanzaki P-310 BB
Type 5 - Two-color grades

Moving from the A756 to the TH320
The following table details the list of commands whose behavior differs between the A756 printer and
the A758, TH420, and TH320 printers. This is due to the physical differences of the 6 dots/mm head in
the A756 and the 8 dots/mm head in the A758, TH420 and TH320.
Command Description Difference between theA756 and the TH320.
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 n1n2 Set absolute starting
position For graphics commands, the position is scaled to best
match A756. In text mode, the equivalent character position
is calculated.
1B 26s c1 c2 n1 d1...nn dn] Define user-defined
character set Since the dots on the TH320 print head are smaller, user defined characters that were used on the A756 printers will
appear smaller on the TH320 printer.
1B 2Amn 1n2d 1...dn Select bit image mode
In A756 emulation mode, graphics are scaled to best match
the size of the graphic in the A756 printer.
1B 33 n Set line spacing This command uses n in terms of n/360 inches. Since the
A756 had a fundamental step of 1/152 inch and the TH320
has a fundamental step of 1/203 inch, the actual line
spacing will not exactly match there quested spacing.
1B 4An Print and feed paper This command uses nin terms of n/360 inches. Since the
A756 had a fundamental step of 1/152 inch and the TH320
has a fundamental step of 1/203 inch, the actual line
spacing will not exactly match there quested spacing.
1B 59 n1 n2 d1...dn Select double-density
graphics In A756 emulation mode, the printer scales the graphics to provide the best match.
1B 5C n 1 n2 Set relative print position The parameter to this command is in units of dots. How
ever, the command moves and aligns to character
positions. In A756 emulation mode, this command
shows many character positions to move based on the
A756 character width in dots (10) versus the TH320 (13).
1B 61 n Select justification This command does true dot resolution alignment for
centering versus character-aligned centering.
1D 2An 1n2d 1...dn] Define down loaded bit
image In A756 emulation mode, this command scales the incoming data to provide a best match to the size of the
image as it printed on A756.
1D2 Fm Print down loaded bit
image In A756 emulation mode, this command scales the incoming data to provide a best match to the size of the
image as it printed on A756.

Moving from the A756, A758 and TH420 to the TH320 (Slip
Differences):
The impact station print zone on the TH420 is 4. 7 inches wide and the print zone on the TH320 is 3.0
inches. To compensate for the narrower print zone on the TH320 the firmware will provide the
following functionality:
For applications that currently use narrow forms using 42 or fewer columns, an option is provided to
delete x leading spaces. No application or form changes should be required.
For applications that use narrow forms using 51 or fewer columns, an option is provided to default to
compressed mode. No application or form changes should be required.
For applications using wide forms that print on less than 51 columns, options 1 and 2 above are
combined with the option to delete trailing spaces. There should be no changes required to the
application but a new form will be required.
For applications using wide forms that print on more than 51 columns, the data will wrap to the next
line. Modification of the application and the form is required if data wrapping is not desired.
Impact Station Print Zone 4.7inches 3inches
Characters/row–Normal Mode 66 42
Characters/row–Compressed Mode 80 51
See Chapter “Programming the Printer” form or details about the slip print zones. Some commands
have new functionality for the slip and can be configured to been able or disabled on the slip. Existing
applications that use these functions on the receipt but not n the slip may need to be disabled
manually for the slip. The default is disabled for the slip.

00 7.2 LPI
01 6.0 LPI
Select Narrow Slip Configuration Option to Ignore n Leading Spaces Code (Hexadecimal)
Code (Hexadecimal) 1F 03 25 08 n
This command is available so TH420 applications can ignore n leading spaces in a 42 - column line of
text.
Range of n 0x00 < n < 0x20 hexadecimal
0<n<32 decimal
n=24 decimal is equivalent to printing the right most 42 columns of the TH420 print zone (24+42=66).
The first non-space in columns 1-n will stop ignoring leading spaces. Text over 42 columns will wrap to
the next line.
Tab (0x09), set column (0x1B0x14n), set absolute position (0x1B0x24NLNH), and set relative position
(0x1B 0x5CNLNH) commands are handled with in the range of ignored leading spaces.
Select TH320 Narrow Slip Configuration Option to Ignore n Leading Spaces
Code (Hexadecimal) 1F 03 25 09 n
This command is available so TH420 applications can ignore n leading spaces in a 51-column line of
compressed text.
Range of n 0x00< n <0x20 hexadecimal
0<n<32 decimal
n=29 decimal is equivalent to printing the right most 51 compressed columns of the TH420 print zone
(29+51= 80).
The first non-space in columns 1-n will stop ignoring leading spaces.
Text over 51 columns will wrap to the next line.
Tab (0x09), set column (0x1B0x14n), set absolute position (0x1B0x24NLNH), and set relative position
(0x1B 0x5CNLNH) commands are handled with in the range of ignored leading spaces.
Select TH320 Narrow slip 51 –column Compressed Print Option
Code (Hexadecimal) 1F 03 25 0A n
When enabled, all normal text is printed in 51 – column compressed print.
This accommodates existing applications printing up to 51 columns on the slip station.
The format will not match the A756/A758/TH420 exactly.
This will not affect rotated print mode (see below).

Select TH320 Delete Slip Trailing Spaces Option
Code (Hexadecimal) 1F 03 25 0B n
When enabled, all trailing spaces on the slip will be deleted.
This accommodates existing applications that send trailing spaces to the slip by not wrapping the
blank text to the next line.
The format will match the A756/A758/TH420 exactly, but a narrower form will be required.
This command will not work for an application that relies on wrapping text to print a line. A print
command is required.
n Delete slip trailing spaces option
00 Disable (default)
01 Enable
Select TH320 (21 and 25-line) Rotated Slip Print Options
Code (Hexadecimal) 1F 03 25 0C n
21-line rotated text print accommodates existing applications, which print 21 or fewer rotated lines (as
read). The format will match the A756/A758/TH420 exactly.
25-line rotated text print accommodates existing applications, which print between 22 and 25 rotated
lines (as read). The format will not match the A756/A758/TH420 exactly.
An A756/A758/TH420 can print up to 33 rotated lines (as read), so those printing 26 or higher rotated
lines, cannot be emulated on theTH320 printer.
n Rotated Print Options
00 21-line (default)
01 25-line
Select TH320 Slip Stop Options
Code (Hexadecimal) 1F 03 0D n
The TH420/A758/A756 mechanism has a positive slip stop for positioning a form at its top right corner.
Some applications rely on a form inserted to this slip stop to print on specific areas of the form. When
the top right corner of the form is at the slip stop, the first print line is 0.7" below the top of form. Some
applications rely on the operator manually positioning a form in order to print on specific areas of the
form.
When n = 01 the form is repositioned to 0.7 inches below the top of the form
The TH320 slip stop override option does not reposition an inserted form. (n = 00)
The TH320 slip stop distance option is triggered at the slip selection command (0x1B 0x63 0x30 0x04)
and positions an inserted form prior to print so that the first line of print will match a TH420/A758/A756.
n Slip Stop Option
00 No slip stop emulation
01 TH420 Slip Stop emulation (default)

Programming the Printer
Overview of Printing Characteristics
Commands control all operations and functions of the printer. This includes selecting the size and
placement of characters and graphics on the receipt or the slip and feeding and cutting the paper. The
programming commands have been organized, in order of hexadecimal code within functional groups.
For this reason, “related” commands may not be listed adjacent to one another.
The TH320 (TH320) standard command set allows it to work with software written for WN or other POS
compliant printers.
Any of the commands may be used in any combination to program a host computer to communicate with
the printer (unless otherwise noted).
For the printer to operate properly within an Ethernet environment, a specific set of commands must
be set.
Some commands listed and described here may not be implemented and are identified as “not
implemented.” If received, they are ignored and not sent to the print buffer as data.
Any non-legal commands have their parameter sent to the print buffer as data.
