I'm new to C, so if I'm overlooking the obvious, please bear with me.
I'm trying to print graphics on a DeskJet+, and am having no problems
except that I can't send ASCII 26 in a string of graphics bytes.
For those not familiar with the Deskjet (but C pros), to print a
row of graphics pixels, you must first put the printer in graphics
mode (I did that). Then send it an Escape, and the following string:
*b###W (... data bytes)
where ### is the number of data bytes that follow.
The data bytes represent 8 pixels, and can take on values from
0 to 255. I can print any byte except ASCII 26!
It isn't the printer, because I can send a 26 in BASIC and
FORTRAN.
Any help would be greatly appreciated (HP and Borland have no clue).
