Gossen THERMAL GRAPHICS PRINTERS IPP 144 - 40 G - Manual (Page 50)

48
The number of dots in the horizontal and vertical direction
is x X 8 dots and y X 8 dots respectively.
x specifies the number of dots in the horizontal direction.
y specifies the number of dots in the vertical direction.
d refers to bitmap image data. The bit for the dot to be
printed is „1“ and the bit for the dot not to be printed is „0“.
The relationship between a download bitmap image and
print data is as follows:
Command: GS * xy [d1] ... [d]x X y X 8
<< Code >>
0x1D , 0x2A , x , y , [d1] [d] x X y x 8
where:
0
≤ x ≤ 255
0 ≤ y ≤ 48, where: x X y ≤ 1536
0 ≤ d ≤ 255
<< Function >>
This command downloads bitmap image into the font ROM,
for example logos. The parameters x and y define the
dimension of the bitmap image.
<< Details >>
Frequent use of this command may cause damage to
the option font ROM. It is recommended to use this
command no more than 10 times a day.
