have the printer connected via a switch box, remove the box and make the
connection directly. If you are using a long parallel or SCSI cable, try a
shorter one.
• The printer is out of paper.
• You are printing to a file or printing PostScript to a SCSI printer or network
printer, and “lp” does not have write permission in /tmp (the TMPDIR
directory).
• The printer cable is plugged into the wrong port at the back of the computer.
You should only connect a parallel printer to a parallel port. Parallel ports are
usually labelled with a pair of forward slashes: “//”. Some workstations (e.g.
SPARCstation 2) do not have built-in parallel ports.
• You are using a SPARCprinter and have the port set to /dev/bpp0 instead of
/dev/lpvi0.
• You are using an HP DeskJet 670TV, 720C, 722C, 820C, 1000C, OfficeJet,
Lexmark Jetprinter 2050, any one of a number of unsupportable
multifunction machines, or some other Windows-only printer. These printers
use proprietary (i.e. undocumented/ unsupported) protocols and are therefore
unsupportable.
Symptom:
PShop prints “PShop Demo Version” over the actual image, the.results file
indicates:
“Could not get VVPRINT license.”
or the.results file indicates:
“Ghostscript command failed.”
and the gs_errs file indicates:
“You are not licensed to run Ghostscript.”
Possible causes and solutions:
• You do not have a license for PShop installed on your system. If you have
your license key, install it using $VV_HOME/bin/installer. If you do not
have a license key, you can obtain an evaluation key from Vividata's website
at http://www.vividata.com by going through the “Free Download”
procedure (you won’t actually need to download the software if you already
