Public bug reported:
The hplip in xenial is not compatible with the versions of cups and dbus
(and various other libraries) in xenial.
The initial symptoms were that after running hp-setup -i (text mode only
box), and attempting to print a test page from hplip, there was no
output. After cancelling that job from http://<host>:631/... and
attempting to print another test page from the CUPS interface, CUPS
reporter 'filter failed'.
Reviewing error_log revealed the message 'unable to open inital device.
quitting'.
While this *sounds* like a device error, hp-levels and hp-clean both
work, so clearly the issue is not with access to the usb device (and the
appropriate /dev/bus/usb/*/* device has group lp and group rw
permissions).
Also some web searching reveals that this can be caused by e.g.
ghostscript errors and is not necessarily indicative of an hardware
device access issue.
Running hp-doctor gives the attached result
hplip version 3.16.3+repack0-1
cups 2.1.3-4
dbus 1.10.6-1ubuntu3
On an up-to-date as of 2016-04-18 01:00:00 -0400 Xenial system installed
from final beta alternate CD.
