How to generate PS file in Windows environment

In order to create a Postscript (PS) file from Windows applications: simply print from the application, selecting a postscript printer and using the printing option "print to file".

A dialog box will open, allowing you to choose the folder in which you wish to create the PostScript file. Choose a name for the file (a .prn extension will be appended to the filename). When you select Save, the printer driver will save the Postscript file in the location you select instead of actually sending the postscript file to the printer. You may need to change the file extension to .ps after file is generated.

However, very likely, using the printer driver for your own printer will result in files that are targeted at that printer, and hence not completely portable. To achieve portability, you will need to install and use another printer driver. Also you may not have any postscript printer with you at the moment. The solution to this is to install a virtual postscript printer, i.e. install printer drivers without actually having the corresponding printer.

Postscript Emulation in printer

Postscript in printers is a page description language and the embodiment of that language on a chip inside a printer. It is an Adobe invention and protected by either copyright or patent law. Anyway, Postscript is open published code, and printer manufactures can choose to license from Adobe, or build their own interpreter based on the PS specifications to avoid the fee structures charged by Adobe. Some do a better job then others.

Generally, PostScript emulation tries to emulate the results of genuine PostScript technology, achieving a printed document that can be very close to the desired result. For most stuff, an emulation will just be as good as the original version. However, the emulation will never achieve results that are precisely the same as a genuine PostScript printer. Some have claimed that certain files fail in emulated PS that work in Adobe. But it is pretty rare case.
