Comment 5 for bug 1038435

Have changed value in models.dat. Has no effect.

Have removed printer, cleared queue, stopped cups, restarted, added printer from scratch.

No luck. Scanning still works, printing doesn't.

Here's typical output in syslog:

Aug 20 11:13:09 minty python: io/hpmud/jd.c 800: mdns lookup HPFFCCF3.local retry 2...
Aug 20 11:13:10 minty python: io/hpmud/jd.c 800: mdns lookup HPFFCCF3.local retry 1...
Aug 20 11:13:10 minty python: io/hpmud/jd.c 800: mdns lookup HPFFCCF3.local retry 2...

which is about all that gets written repeatedly when hp-systray queries the device or scan is selected

and this when a test print is attempted:

Aug 20 11:21:11 minty python: io/hpmud/jd.c 800: mdns lookup HPFFCCF3.local retry 2

suspect this doesn't help at all.
