I don't mean to meddle here, and I might be way off base.

But FYI, printing.el uses ghostview (gsview32.exe on Windows), which IIRC comes
with ghostscript (gsprint.exe on Windows), in order to show buffer contents. You
might take a look at that.

Look at, for instance, menu item Printing > PostScript Preview > Buffer > 1-up.
The menus are pretty much identical between PostScript Preview and Printing, and
between viewing/printing a file and viewing/printing a buffer.

HTH.
