I just posted this on linuxprinting.foomatic.devel, but I guess some here might have the same problem, namely that the HPLIP printer drivers fail when combined with CUPS' Backend Error Handler:
To fully utilize the capabilities of our HP LaserJets I recently
installed HPLIP and was quite pissed off at the fact that it doesn't
work with BEH---I had almost forgotten how much work BEH had saved me
killing users' stuck print jobs and manually restarting the printer in
CUPS. So I started digging in the HPLIP sources today and got it working
with a trivial patch:
# diff /usr/share/hplip/base/device.py.orig
# /usr/share/hplip/base/device.py
47c47
< pat_deviceuri =
re.compile(r"""(.*?):/(.*?)/(\S*?)\?(?:serial=(\S*)|device=(\S*)|ip=(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}[^&]*))(?:&port=(\d))?""",
re.IGNORECASE)

> re.IGNORECASE)
I.e. I just removed the first question mark in the RE to make it greedy
again. Now it seems to work fine with my printers.conf:
DeviceURI beh:/1/3/120/cupspykota:hp:/net/HP_LaserJet_4100_Series?ip=12.34.56.78
This hasn't been tested extensively yet so I may be missing something
and the patch might break more that it fixes on other configs, but maybe
some of you would like to give it a try. Comments welcome.
cheers!
