I have an old medical equipment, with a software which works only with windows98, no update available, my problem is i can't find a printer compatible with win98, also the software prints only on parallel port (LPT),
So now am looking for some trick to print into a file (image, pdf, ...) using a virtual printer or anything, so any help or idea will be appreaciated !
Try CutePDF. CutePDF Writer installs itself as a "printer subsystem".
