Direct Graphic Write

Description Use this command to load binary graphic data directly into the Image Buffer memory for immediate printing. The printer does not store graphic data sent directly to the image buffer.

The graphic data is lost when the image has finished printing, power is removed or the printer is reset. Commands that size (Q and q) or clear (N and M) the image buffer will also remove graphic image data.

Syntax GWp1,p2,p3,p4,DATA

Parameters This table identifies the parameters for this format:

Parameters			Details
p1	=	Horizontal start	Horizontal start position (X) in dots.
		position
p2	=	Vertical start position	Vertical start position (Y) in dots.
p3	= Width of graphic		Width of graphic in bytes. Eight (8) dots = one (1) byte of
			data.
p4	= Length of graphic		Length of graphic in dots (or print lines)
DATA			Raw binary data without graphic file formatting. Data must
			be in bytes. Multiply the width in bytes (p3) by the number of
			print lines (p4) for the total amount of graphic data. The
