Downloadable Fonts
maintains a 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 4 parameters are included in the FONT file when it is created:
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.
