This is a round-about workaround if you have a printer that doesn't have in-box support or an out-of-business/unsupported printer manufacturer.

If you have a printer that can 'talk' PCL and/or Postscript, try the HP Universal Print Driver Series for PCL 5, PCL 6 or PostScript.

If you have a LaserJet 4MV like I do with the default amount of RAM installed inside, you'll want to crank down the default amount of RAM available from 6MB to whatever the amount of RAM is available on your particular printer, if you want to be able to print complex PostScript documents.
