Hi Guys,
I have this program written in pascal that dumps its output in HPGL format
direct to the LPT1 port. This is usually printed by a thermal plotter but as
I can no longer get thermal paper for the plotter I was wondering if anyone
knows a way to force WinXP to capture output send to LPT1: and store it in a
file somewhere?

Cheers

Have you tried "print to file?" Do a search and you will find
instructions on how to do this, both from a prompt and possibly from a
menu. I am not familiar with HPGL format, but if it can be viewed one
would think it could be printed.

"Print to file" is an option in WinXP's print dialog. He has a piece of
software written to send data to the LPT1: (parallel) port. There will be no
print dialogs and options!

There's loads of stuff
