Franz,

I have the postscript module in both the LJ5 and the 2500C. Regardless,
non-PS output is filtered through either gs or gutenprint (when installed)
first.

No doubt. It's printed duplex nicely here for more than 8 years. I need to
find out why it stopped.

Gutenprint does only black-and-white with the ColorPro 2500C. That's why I
bought the PrintPro drivers years ago. Same printers, same drivers. If they
worked then they should still be working now.
