Maybe you want to print to PDF. maybe you’ve used programs like: http://www.pdf995.com/
WARNING: THIS DOESN’T YET WORK WITH VISTA!
FYI, a lot of the Windows PDF printers are simply generic PS printers which are connected to ghostscript (which has PS-PDF conversion functionality). http://www.cs.wisc.edu/~ghost/
In fact, you can make your own windows PDF printer by downloading ghostscript and redmon
http://www.cs.wisc.edu/~ghost/redmon/index.htm
“The RedMon port monitor redirects a special printer port to a program. … RedMon can be used with any program that accepts data on standard input.Using RedMon you create redirected printer ports. If you connect a Windows printer driver to the redirected printer port, all data sent to the redirected port will be forwarded by RedMon to the standard input of a program. This program is then responsible for processing the data and producing new output.”
I’ve done this and it’s easy to do.
Here are two step-by-step tutorials to creating a free PDFWriter using Ghostscript:
