2.27 GS * Define download bit image
[FORMAT] <1D>H<2A>H<x><y><d1>…<d (x * y * 8)>
[RANGE] 0≦ x ≦30H
0≦ y ≦30H
d = x * y * 8
[FUNCTION] Defines a download bit image of the number of dots specified by x*8 and y*8.
* x specifies the bytes in the horizontal direction and y specifies the number bytes in the
vertical direction.
[CAUTION] * The number of dots in the horizontal direction is x x 8 and in the vertical direction is y x 8.
* If x * y is out of the specified range (48 x 48), this command is ignored.
* Parameter d is bit-image data. A bit corresponding to printing dot is 1 and not to printing is
0.
* The download bit image is effective until the printer is re-defined, reset or the power is
turned off.
* See FS q command for bit layout in data bytes.
* Bit image, user defined characters (ESC &), print bitmap block (GS q) and print raster bit
image (GS v 0) shares the same memory. Sending this command will discard user
defined characters or bitmap block.
2.28 GS / Print download bit image
[FORMAT] <1D>H<2F>H<n>
[RANGE] n – ignored
[FUNCTION] Prints download bit image set by GS * command.
[CAUTION] * This command may interfere with ordinary text printing command if sent while text line has
not been printed.
* This command is ignored if a download bit image has not been defined or is deleted, for
example, using ESC & command.
