Bug#572247: hplip: start/stop button should fail with permission error dialog if not member of lpadmin
Package: hplip
Version: 3.9.12-2
Severity: normal
Hi.
As far as I can understand, one needs to be a member of the lpadmin group so that the cups client library part of hp-toolbox can start/stop/resume printers managed by cups in the backend.
Now, if one executes hp-toolbox without being a member of lpadmin, the start/stop button will be useless, failing silently.
I already filed a bug upstream about the fact that it fails silently instead of having some GUI dialog for error message (https://bugs.launchpad.net/hplip/+bug/530746).
Now, I think that it should be documented somewhere that such lpadmin group membership is required (assuming that it's Debian-specific), and/or be mentioned in the error message instead of a very generic error.
Maybe hp-check could check for this too.
Thanks in advance.
Best regards,

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper
dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied
tarball has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time
dependencies).
