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 3 D [23/Jun/2018:21:49:26 +1000] [Job 5] Set job-printer-state-message to "ready to print", curren t level=INFO 4 D [23/Jun/2018:21:49:26 +1000] Discarding unused job-progress event... 5 D [23/Jun/2018:21:49:26 +1000] cupsdMarkDirty(-----S) 6 D [23/Jun/2018:21:49:26 +1000] cupsdSetBusyState: newbusy="Printing jobs and dirty files", busy= "Printing jobs and dirty files" 7 D [23/Jun/2018:21:49:26 +1000] [Notifier] state=3 8 D [23/Jun/2018:21:49:26 +1000] [Notifier] PrinterStateChanged 9 D [23/Jun/2018:21:49:26 +1000] cupsdReadClient: 24 POST / HTTP/1.1 10 D [23/Jun/2018:21:49:26 +1000] cupsdSetBusyState: newbusy="Active clients, printing jobs, and di rty files", busy="Printing jobs and dirty files" 11 D [23/Jun/2018:21:49:26 +1000] cupsdAuthorize: No authentication data provided. 12 D [23/Jun/2018:21:49:26 +1000] cupsdReadClient: 24 1.1 CUPS-Get-Printers 1 13 D [23/Jun/2018:21:49:26 +1000] CUPS-Get-Printers 14 D [23/Jun/2018:21:49:26 +1000] Returning IPP successful-ok for CUPS-Get-Printers (no URI) from l ocalhost 15 D [23/Jun/2018:21:49:26 +1000] PID 9829 (/usr/lib/cups/backend/hp) exited with no errors. 16 D [23/Jun/2018:21:49:26 +1000] cupsdMarkDirty(-----S) 17 D [23/Jun/2018:21:49:26 +1000] cupsdSetBusyState: newbusy="Active clients, printing jobs, and di rty files", busy="Active clients, printing jobs, and dirty files" 18 I [23/Jun/2018:21:49:26 +1000] [Job 5] Job completed. 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. Erik
