7.4.1.1 Save Compressed FONT to RAM (D127).
The following is the format of the ^D127 command when used to store a compressed FONT
file into RAM.
^A<RAM Memory Slot Number>^D127<CR>
<Rotation> <Count> <Image Data>
Where:
<RAM Memory Slot Number> is the memory slot location (1-255) where the FONT will be
saved in the printer’s RAM memory. The printer uses the same TCI of “8” to select
downloadable fonts or graphics for storage into RAM. Therefore a font and a graphic
cannot have the same Slot Number or CGN number.
<Rotation> is an 8-bit integer, 0 for an upright FONT and 1 for a FONT rotated 90-degrees
counter-clockwise.
<Count> is a 32-bit integer, least significant byte first. This is the number of uncompressed
bytes that the FONT uses, not the number of bytes that will actually be transmitted. Due to
compression, the number of bytes transmitted will normally be less than this number.
<Image Data> is the compressed binary image.
7.4.1.2
Save Compressed FONT to FLASH (D135)
The following is the format of the ^D135 command when used to store a compressed FONT
file into FLASH.
^A<FLASH Memory Slot Number>^D135<CR>
<Rotation> <Count> <Image Data>
Where:
<FLASH Memory Slot Number> is the memory slot location (1-120) where the FONT will be
saved in the printer’s FLASH memory. The printer uses the same TCI of “7” to select
downloadable fonts or graphics for storage into FLASH memory. Therefore a font and a
graphic cannot have the same Slot Number or CGN number.
<Rotation> is an 8-bit integer, 0 for an upright FONT and 1 for a FONT rotated 90-degrees
counter-clockwise.
<Count> is a 32-bit integer, least significant byte first. This is the number of uncompressed
bytes that the FONT uses, not the number of bytes that will actually be transmitted. Due to
compression, the number of bytes transmitted will normally be less than this number.
<Image Data> is the compressed binary image.
7.4.2 Uncompressed FONT to RAM (^D104)
This command allows graphic and/or font images (fonts must be less than 64KB
uncompressed) to be transmitted in ASCII-HEX, thereby allowing all data to pass over 7 or
