Description Tim Waugh 2006-12-06 13:40:26 UTC

Description of problem:
The HPLIP service should only be running when an HP device it drives is
connected.  Can use HAL for that.

Comment 1 P Jones 2006-12-19 18:01:49 UTC

I'm not sure if the problem I am recently experiencing has to do with this bug.
Please let me know if not and I'll file a new bug. This occurs on an up to date
(as of 12/19/06) FC6.

I can not print to a JetDirect connected HP OfficeJet 7110 All In One unless I
scan something first using XSane.

I've tried this with SElinux and firewall off, and on, the result is the same.

Setup of the printer is done using hp-setup in GUI mode, and printing a test
page right after setup works. Reboot, and then printing does not work unless
scanning first, which works fine first time.

Please file a separate bug report.  Thanks.

What about network connected printers?  Can you detect them with avahi and do
the same?

I guess the printers would already be configured, one way or another via
system-config-printer/cups. We should be able to start up HPLIP after cups if a
printer requires it. But what about network scanners?

I guess the best bet is to make HPLIP a D-Bus service that can startup on
demand, and die when nothing uses it.

I don't think that would work for things like low supply notices.  (Not sure if
hplip is even doing anything like that right now though)

Comment 7 Tim Waugh 2007-05-09 08:51:47 UTC

HPLIP does give marker-supply-low-warning notices, yes, but CUPS keeps them
persistent if HPLIP disappears after issuing them.  They are part of the CUPS
printer's printer-state-reasons attribute.

Comment 8 Tim Waugh 2007-06-29 16:51:12 UTC

HPLIP 2.7.6 is now daemon-less.
