	I would like to be able to print out a VGA graphics screen
from within a TURBO C 2.0 program, and have the program continue to execute
while the screen is printing.  The system which I have presently isn't working:
I am using PRTSC as a GRAPHICS.COM replacement and DOS PRINT for spooling.
Unfortunately PRINT appears to be bypassed when a PrintScreen request is
issued.  The shareware print spooler DMP drops characters when spooling,
and the printer never even gets into graphics mode.
	I'm starting to think that this is the wrong approach, and that I 
should manually print the screen from within the program (in a print
spooler compatible way -- whatever that is...).  If anyone can offer any
programming tips, or pointers to exiting code/utilities, I would really
appreciate is, as this is for a project that needs to be done in about a week.
	Thanks in advance for any help!
