I have a Brady 300 MVP plus Thermal Label printer. I had a bug where after
printing approx 50 Labels the printer would stop printing, afterwards the
printer would begin loosing pixels on the print head.
Come to find out, the printer's Firmware (Maybe mine is old) does not
handle the RAM filling up so gracefully. the printer when locked would
leave the printhead on, thus destroying parts of the printhead that were
on when it locked.
I looked through the filter's code, looks like there should a Command to
remove the Image data from memory.
Looks like this printer is a copy of a 300 DPI Z4M printer.
Here is the diff I made from my updated <CUPS_SRC>/filters/rastertolabel.c
I couldn't find a listing for this driver on the printer drivers page, so
I couldn't post it there, Hope this helps someone.
