"DATA"
Parameters p
1
X-position in printer dots.
p

Y-position in printer dots.
p

Number of bytes across the graphic (8 dots = 1 byte).
p
4
Number of dot rows going down the graphic.
"DATA" The graphic data in 1-bit (black & white) PCX format.
Remarks Use this command instead of GM for temporarily used graphics, for example
images that change between each label. Not only is this method faster, but
it also prolongs the life of the fl ash memory as the graphics are downloaded
directly to DRAM.
The printer’s fi rmware will calculate exactly how much data to expect based
on p
3
and p
