Yes, I've seen it, but that's it: another program that I have to
install, which I want to avoid.

I'd be happy if I just do "printer.Print(file.pdf/.ps)" and walá, the
printing just starts (in 98,2000,XP... sounds like a dream), without
having another window opened. If it opens, but then closes, it's
perfect too. I have tried installing Ghostscript, and having a .ps when
I order that file to print, it does the job. The thing here is that I
have to install it.

All this has to be easilly installed (with InnoSetup, for example),
because I have to install it on 70 offices. So I can't leave it to
another installation process. All of these offices have a dot matrix
printers Epson LX-300, which has PostScript level 3 built-in.

Where can I find how to send a .ps directly to the printer?
