Chapter 3: 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 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 operation of various printers may be emulated by the
commands, including the following:
• A760 native
• A758 emulation
• A756 emulation
The A760’s standard command set allows it to work
with software written for CognitiveTPG or other POS
compliant printers.
Any of the commands may be used in any combination to
program a host computer to communicate with the printer
(unless otherwise noted). For Ethernet use a specific set of commands must be set
for the printer to operate properly. These commands are
listed together as a chart on page 20 and individually
within the master commands listings.
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.
Comparison to A756
The following table details the list of commands whose behavior differs among the
A756, A758, and A760 because of the physical differences of a 6 dots/mm head (A756)
versus an 8 dots/mm head (A758 and A760).
Command Description Difference between previous product
and new product 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 A756. 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 A760 printhead are smaller, user
defined characters that were used on the previous printers
will appear smaller on the A760 printer.
1B 2A m n1 n2 d1...dn Select bit image mode In A756 emulation mode, graphics are scaled to best
match the size of the graphic in the A756 printer.
