Well, I don't know the 'other' OS but in Linux 'Print' prints to a .ps file.
I just tried it (actually, I never noticed the 'print' item in the menu before... ) and a file called x.ps appeared in the directory from which I started PD.
_I think_ that if Print behaves the same way on NT, printing .ps files to the printer should work afterwards.
The File->Print (ctrl-p) function does not seem to work. this is on NT and its version 3.6. Does anybody else have problems printing out a patch to paper?
