^A ^D COMMAND
33 Display Model and Revision Number
5.12 Memory Commands
These commands offer special functions related to clearing, storing, and processing data in
the RAM and FLASH memory.
The printer can store up to 128 FORMAT files into the printer’s volatile RAM memory and
another 128 files into non-volatile FLASH memory. Once stored, these files may be loaded
from memory rather than having to be sent down thru the serial port. Formats are retained
even after power has been cycled when stored in FLASH memory. Formats stored in RAM
will be lost when the printer is turned “OFF.”
The printer may be configured through software switch #2 (^D22 command) to automatically
process a specific format from the FLASH memory (power up format) when the printer is
turned “ON.” The printer treats the stored formats as if they were sent through the serial
port.
XX
54 Send Format from RAM to Port: The ^Axx specifies the slot number
(1-128) where the format file is stored in RAM. This may be used to read what
is stored in each memory slot.
XX
58 Process Format Saved in RAM: The ^Axx selects which stored format to
process (1-128). This command is processed in the same was as if the
format was sent directly to the port.
XX
59 Save Formats to RAM. (volatile)
The ^Axx selects the memory slot (1- 128) into which the format is to be
saved. A format file must be terminated by an ESC (HEX 1B) or “[“(left
bracket) character to save the format.

not with downloadable fonts and/or graphics.

that have been stored in RAM. This command does not affect fonts and
graphics that have been downloaded and stored into the FONT flash memory.
Use the ^D17 to erase FONT flash memory.
