GW Command - Direct Graphic Write

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

The graphic data is lost when the image has fin- ished 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,p4DATA￿

Parameters p1 = Horizontal start position (X) in dots. p2 = Vertical start position (Y) in dots.

p3 = Width of graphic in bytes. Eight (8) dots = One (1) byte of data

p4 = Length of graphic in dots (or print lines).

DATA = Raw binary data without graphic file formatting. Data must be in bytes. Multi- ply the width in bytes (p3) by the num- ber of print lines (p4) for the total amount of graphic data. The printer au- tomatically calculates the exact size of the data block based upon this formula.
