Very Computer

Does any AIXer have experience with the QMS 1700 postscript printer?
We have one connected to the parallel port of a 320H. The problem is that
randomly about 1 out of 3 times print jobs disappear.

I monitored the spooling directories and queues and found that all the
files were transmitted to the printer seemingly ok (the Data indicator
on the printer console was on during the transmission).

I've modified the virtual printer to generate "%%EndOfDocument" at EOJ
and requested QMS to come to update the firmware to version 22D. However,
the problem persists.

Any clue is appreciated.

The first thing I would do if verify that printing your files
works ok when cat'ing directly to the printer device.  You
first need to put the device driver in passthru mode.  For
example:

    splp -p+ lp0
    cat myfile.ps > /dev/lp0

Does that work?  If not you have a device configuration problem,
cabling problem, or printer hardware problem.

If that consistently DOES work, then there would appear to
be a a problem in the spooling or backend processing of the
job.  A setup that should work with most any PostScript
printer is a device type of 'Other Parallel Printer' and
a virtual printer type of 'PostScript Printer'.

Also, check for error messages in the directory:

   /var/spool/lpd/pio (AIX 3.2.x)
   /usr/lpd/pio   (AIX 3.1.x)

Hope this helps.
