I was just also receiving a code=12 error message and by adding myself to
the scanner group. I am now able to access the device correctly through
hp-toolbox.
Yes, this fixed the problem.
code=12 was a bit obtuse for "you are not a member of the group scanner"
Arthur,
Excellent, glad we have made some progress. But you are right the error
message isn't sensible and the scanner group doesn't make sense for running
hp-toolbox. The reason is that the USB device ownership is set lp.scanner,
this is a Debian/ Ubuntu modification.
Arthur. Wrt your ink supply Traceback, please file a new bug report, with
upstream preferably, as you will see if you try and file a report with hplip
2.8.6.
Till, the upstream file ./data/rules/55-hpmud.rules sets the USB device
OWNER="root", GROUP="lp", whilst the debian/ubuntu version
debian/55-hpmud.rules sets OWNER="lp", GROUP="scanner".
This has the effect that everyone trying to use hplip needs to be a member of
group scanner to use things such as hp-toolbox, rather than the expected lp
group. How would you feel if we reverted 55-hpmud.rules back to the upstream
default of OWNER="root", GROUP="lp".
