How to create Postscript files on a Windows machine from any application which can print:

Setup a printer designated to print to a file rather than a real printer like this: Go to Control Panel, Printers, Add Printer, Choose Local printer then Next. Select port type of "FILE" from the list of ports Pick Apple Color LW 12/220 PS (This is a fairly standard color PS printer) Finish installing the printer. Select "Print Test Page" if you like. You will get a prompt for the file name to create. Enter something like "test001.ps" for the file name.

You will now have a Postscript file named test001.ps wherever you designated the file to be created. This will likely be at c:\test001.ps unless you designated otherwise.

You can now create a Postscript file whenever you want by printing from your windows application and selecting the printer you just defined. You will always be prompted for a file name when you select this printer.
