Thanks for the offer. We may take you up on it. Jan informs us that we can
also use Ghostscript in order to print Postscript output on non-Postscript
printers.

One other note on printers. Besides testing with printouts from my ten year
old (works great) HP LJ4 (600x600 dpi), I tried printing with my six yr old
HP InkJet printer, model 820 Cxi (600 dpi or 300 C-REt with mixed text and
graphics). The output from the 820 Cxi has always looked great but is not
quite as fine and sharp as the laser. Anyway, I tried printing the barcodes
with it. The Cue Cat can read the barcodes at 24 points from the InkJet
about as well as it reads 22 points from the laser. So it may be that an
InkJet could be perfectly usable for this application. It will probably be
less work and more reliable to just use a Postscript laser for the demo, but
it's definitely worth keeping in mind. With InJet printers getting better
and cheaper all the time, we may want to investigate using them later. In
any case, if someone asks about printers at the demo, we can say that the
barcodes have been successfully tested on an InkJet printer.
