Programming the Printer
Overview of commands
Commands control all operations and functions of the printer. This includes selecting the size and
placement of characters and graphics on the receipt to 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 operation of various printers may be emulated by the commands, including the following:

Native

A793/TH210/TH210-2/A794

TH230

LEGACY
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 and are identified as “not
implemented.” If received, they are ignored and not sent to the print buffer as data.
Any nonlegal commands have their parameter sent to the print buffer as data.
Comparison to A793
The following table details the list of commands whose behavior differs between the A793,
TH210/TH210-2/A794, and TH250 because of the physical differences of a 6 dots/mm head (A793)
versus an 8 dots/mm head (TH210/TH210-2/A794 and TH250).
Command Description Difference between previous product and new
product emulation mode
15n 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 n 1
n 2
Set absolute starting
position For graphics commands, the position is scaled to
best match A793. In text mode, the equivalent
character position is calculated.
1B 26 s c 1
c 2 n 1 d 1
... nn dn ]
Define user-defined
character set Since the dots on the TH250 printhead are
smaller, user defined characters that were used
on the previous printers will appear smaller on
the TH250 printer.
1B 2A m
n 1 n 2
d 1... dn
Select bit image
mode In A793 emulation mode, graphics are scaled to
best match the size of the graphic in the A793
printer.
1B 33 n Set line spacing This command uses n in terms of n/360 inches.
