6.5.2 Save Compressed Graphics to FLASH (D133)
The following is the format of the ^D133 command when used to store a compressed
GRAPHIC image file into FLASH.
^A<FLASH Memory Slot Number>^D133<CR>
<Rotation> <Count> <Image Data>
Where:
<FLASH Memory Slot Number> is the memory slot location (1-120) where the GRAPHIC
will be saved in the printer's FLASH memory. The printer uses the same TCI of "7" to select
downloadable fonts or graphics. 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 GRAPHIC and 1 for a GRAPHIC rotated 90-
degrees counter-clockwise.
<Count> is a 32-bit integer, least significant byte first. This is the number of uncompressed
bytes that the GRAPHIC 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.
6.6 Downloadable Graphics Commands
The following commands refer to the use of downloadable graphics:
^A ^D COMMAND
100 Clear User RAM: This command clears all downloadable fonts, graphics, and
stored label formats.
101 List RAM Memory Bytes Available: The printer will send the ">" character
followed by the amount of available bytes and then finally a "<" character. (i.e.
>192690<)
XX 106 Save GRAPHICs or FONTs into RAM Memory without Compression:
This command is intended for legacy support only and Microcom Corporation
recommends either the ^D104 or ^D107 commands. Fonts must be less than
64KB for this command to function.
XX 107 Save GRAPHICs or FONTs into RAM Memory using Binary Compression:
XX 133 Save Compressed GRAPHIC to FLASH.
