March 199942
Commands control all operations and functions of the printer; from selecting the size
and placement of characters and graphics on the receipt to feeding and cutting the
paper. The operation of various printers may be emulated by the commands, including
the following:
♦ Axiohm A793
♦ Axiohm A794 Native Mode
♦ Axiohm APOS
♦ Epson TM-T88
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.
