Printing to a PostScript file from Word

I run the an agencies print shop and we use overlays that are stored on two Ricoh Pro 8220 S printers.  Nobody I've spoken to at Ricoh or with our maintenance vendor have any idea as to how we are writing to the hard drive on the printers.  The problem I have is that the PostScript driver I have is so old, it won't install on Windows 10.  I'm trying to "Print" a Word Document to a Postscript file so I can save it to each printer for a new version of a letter.  Any help is appreciated.  I need to be able to select the PostScript print driver from the printers menu and write the PostScript file.
