Printer Commands
maintains an address table that tells where each FONT CGN # is stored in
FLASH.
The CGN # is established by the user when the FONT download file is created
using the font converter program. Since this is an arbitrary number picked by
the user, it is possible to create two separate FONT files with the same CGN
#. In fact, many FONT files could be created using the same CGN #. For the
printer to function properly, each FONT in FLASH must have a unique CGN #.
If a FONT is downloaded that has the same CGN # as a FONT that is already
stored in FLASH, then an error message is sent back indicating a Duplicate
CGN error.
The printer's FLASH is nonvolatile, so FONTS that are downloaded using the
^D135 will be stored in FLASH memory until specifically erased by the user.
The following 3 parameters are included in the FONT file when it is created:
1. Memory destination: RAM or FLASH
2. Memory File #: 1255 (this is the CGN #)
3. Rotation: 0°, 90°, 180°, or 270°
How to save a FONT to FLASH:
Hint: After the FONT file has been sent, the ^D119 command may be used to verify
that the new FONT is now available in FLASH.
^A ^D COMMAND
XX 136 Delete a FONT from RAM.
^A0 deletes all FONTS from RAM
^Axx deletes the FONT stored in RAM Slot #xx
Valid values for Axx are 1 to 255. The user selects the RAM memory Slot #xx
that will be cleared.
Hint: After the FONT file has been deleted, the ^D119 command may be used to
verify that Slot #xx is now available in RAM. The FONT may extend over
several slots and the ^D119 will indicate how many slots are used.
XX 137 Delete a FONT from FLASH.
^A0 deletes all FONTS from FLASH
^Ax deletes the FONT stored in FLASH Slot #x
Valid values for Axx are A1 to A255. The user selects the FLASH memory
Slot #xx that will be cleared.

1. Create the special FONT download file with FLASH set as the
memory destination,
2. Send the file to the printer using a standard communications
program set for 8 data bits, no parity, 1 stop bit.
