Fundamentals of Dot Matrix Printing

Note: If we used OIL" or CHR$(76)
instead of "K;' we would be asking
Gemini for high-resolution graphics.
If we used "y" orCHR$(121), we would
be asking for high-resolution graphics
with double speed, and if we used
"z" or CHR$(122), we would be asking
for ultra-high-resolution graphics at
normal speed.
n1 and n2 represent the set of ASCII
codes that define how many columns
of graphics to print on a line. If you
want to print "x" number of columns
of graphics on a line, then:
n1 is the remainder of x/256, and
n2 is the quotient of x/256
Note: For those of you who are
computer-wise and curious:
n1
=
x
MODULO 256, and n2
=
INTEGER of
x/256
What does all this mean to the rest of us? The following table
might help.
If the number
of columns,x,

then
ranges from:

Remember: Gemini-10X can only print up to 480 columns in
low-resolution mode, 960 columns in high-resolution mode, and
1920 columns in ultra-high-resolution mode. The Gemini-1SX can
print 816 columns in low resolution, 1632 in high-resolution, and
3264 in ultra-high-resolution.
