Printer Commands
^A ^D COMMAND
101 Send User RAM Available: The printer will send the number of free or
available bytes to the serial port (i.e. >192480<).
Use the D119 command for more detailed reporting.
XX 104 Save ASCII Fonts to RAM: The ^Axx specifies which memory file # (CGN #)
the FONT will use (1-255). This command should be used with an ASCII-HEX
file that contains only printable characters less than 80 HEX. These FONTS
are "extended non-compressed", meaning that they can be greater than 64KB
in size. This command supports fonts greater than 64KB.
XX 105 Delete Graphics from RAM
^A0 deletes ALL graphics from RAM.
^Ax deletes the graphics in slot #x.
xxyy 107 Save Compressed GRAPHICS to RAM.
(See Chapter 6, Downloadable Graphics)
119 Display Memory Allocation.
This command shows how all of the RAM and FLASH memory is being used
Example display from the ^D119 command:
Ram Based Fonts/Graphics(TCI=8) - [file number(CGN), size, type]
[2,4625, Font set]
Ram Based Formats - [file number, size]
[2,176]  Slot #2 in FORMAT RAM has a FORMAT that is 176 bytes.
Total Ram Memory Available - 258335  There are 258,335 bytes of RAM
Flash Based Fonts/Graphics(TCI=7) - [file number(CGN), banks used, type]
[1,1, Graphic]
Font/Graphic Flash Memory Banks Available - 119  There are 119 banks of 64KB open.
Flash Based Formats - [file number, size]
[1,176]  Slot #1 of FORMAT flash has a FORMAT file that is 176 bytes.
Format Flash Memory Available - 65359  There are 65,359bytes of FORMAT flash open.
Label Memory - [size, available]
[43231,41618]  The difference is the amount of memory to process current format.
NOTES: RAM GRAPHICS can extend beyond the starting slot # into
sequential ones. RAM formats are numbered #1 to #128 (RAM FONTS are
limited to 64K in size.)
122 Display Available FONT/GRAPHICS FLASH memory.
This command is used to display the amount of FONT/GRAPHICS FLASH
memory available in bytes in the form >xxxxxxx< where xxxxxxx is the number
of available bytes.
