Ok guru's...... Figure this one..

Has anyone had any experiences with printing from within 
a program?  I wrote a program that creates a file and
sends it to a printer.  I am using DJGPP and the ALLEGRO
library.  When it goes to the printer, the printer's data 
light flashes for a few seconds, and then the error light 
comes on.  I originally tried sending the file to stdprn, 
and thought this is where the problem was.  So then I 
wrote the output to a file and then did a 
"COPY /B FILENAME LPT1:"  This worked. Now if I take the 
same file, and from within my program issue...

system ("copy /B filename LPT1:");  

It starts to go to the printer, but then the error 
light comes on.  Now if I exit my program and use
the old "COPY /B FILENAME LPT1:" from the command
prompt the same file works.. 

This has me really confused... What is worse is that
if I take a file designed for a different printer, and
try this, it seems to work ok.. Anyone have any ideas?
