F undamenta/s of Dot Matrix Printing
Note: If we used 'I" or CHR$(76)
instead of "K:' we would be asking
Gemini for high-resolution graphics.
If we used "y" or CHR$(121), we would
be asking for high-resolution graphics
with double speed, and if we used
"2" or CHR$(122), we would be asking
for ultra-high-resolution graphics at
normal speed.
nl 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:
nl 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:
nl = x
MODULO 256, and n2 = INTEGER of
xl256
What does all this mean to the rest of us? The following table
might help.
If the number
of columns,x,
ranges from:
1 to 255
256to 511
512 to 767
768 to 1023
1024 to 1279
1280 to 1535
1536 to 1791
1792 to 1920
then,
nl
Is

x- 512
x- 768

Remember: Gemini-70X 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-15Xcan
print 816 columns in low resolution, 1632 in high-resolution, and
3264 in ultra-high-resolution.
