I recently posted a similar question but with inadequate details.

I have a program that I ported from Borland compilers to DJGPP.  I
converted the routines that do graphics to use the GRX library.
Previously printing of graphics was done using the DOS Graphics program
that does a screen capture and dump to the printer invoked by the
prtscrn key.  This unfortunately works incorrectly now.

I can dump text screen information to the printer with no problem but
when I try to print graphics I get either a blank page or a totally
black page.  My theory is that GRX maps the graphics screen to a block
of memory that DOS's Graphics program doesn't know about and thus 
prints out garbage from a totally unrelated block of memory.

I really hope that this can be made to work since if it doesn't I will
have to write my own printer drivers!  How might I remedy this situation?
Any help would be GREATLY appreciated!

Thanks in advance.
