Re: Have managed a CUPS printer addition, but the queue is a black hole.




Aargh! Apologies for committing a subthread hijack. That wasn't intended.

The new CUPS & HP-LaserJet-3050 addition prints the printer self-test
page immediately, the CUPS test page after several minutes, but other
print jobs not at all. Again, printing from xpdf, the job is queued:

$ lpq
HP-LaserJet-3050 is ready and printing
Rank    Owner   Job     File(s)                         Total Size
active  (null)  5       untitled                        8192 bytes

then

$ lpq
HP-LaserJet-3050 is ready
no entries

but no printer output.

In /var/log/cups/error_log, for that job, we see:

  2 I [23/Jun/2018:21:49:26 +1000] [Job 5] ready to print

but still nothing printed.

The CUPS test page includes "Driver: HP3380_6.PPD". I don't know if it
has selected the best one, or if that's relevant to this print job
evaporation.
