George:
Perhaps I misunderstood the question - but can't you
just print to the LPT in the same way as DOS programs
do? Using puts() and printf()?

well, maybe it's just that simple, the demo's seem'd to be bit map
approaches. i'll give that a try.
thanks

Irv, I did what you suggested and it was really puzzling. It printed things
fine to the printer but the first 2-3 lines of the printout that should have
been at the top of the page were at the bottom of the page. I had no idea
what caused this....after opening lpt am I supposed to do something else to
position the output to the top?

By printing directly to the printer you now have to
deal
with the peculiarities of each printer brand. Remember
the "escape codes" which were often different for
different
brands and even different models of the same brand?
You'll probably have to dig up some manuals, and find
a reset or clear-the-buffer or top-of-page code to
send
to the printer. Perhaps also some codes to set the
margins, fonts (if available), etc. etc.
Then when your client changes printers, do it all over
again. Printing is one area where Windows is actually
a big improvement over what we had before.
