Recently printing stopped working on my server, and it turns out I didn't have PyQt4 installed. After emerging PyQt4 (just with dbus and svg USE, -X) printing worked. Should the dependency be changed to always require PyQt4 with dbus USE-flag (hp-check tool seems to suggest that), but make the dependency on PyQt4 with X USE flag optional? Let me know if I can do some further tests for you.

According to (1) pyqt and pyqt-dbus are only required for the gui parts of hplip. Maybe this has changed with recent versions and the page is not up to date. I will take a closer look when I have access to my gentoo machines. (1) http://hplipopensource.com/hplip-web/install/manual/distros/other.html
Are there any error messages in /var/log/cups or /var/log/messages?

Okay I had some time looking into this. I recompiled PyQt4 without the dbus flag, restarted cups and hplip and I had no problems with printing from Openoffice.. Can you try again with LogLevel set to debug.

I have a CM1312nfi. The original post advocated always requiring PyQt4[dbus]. It is my opinion that this should continue to be gated by the qt4 use flag. All three ebuilds in the tree (3.9.12, 3.10.5, 3.10.5) have RDEPEND = qt4? ( PyQt4[dbus,X] )
Actually, now that I think about this some more, it could be that he was having the same issue that I just opened a new bug for. (Bug 331163) hplip seems to require dbus-python all the time and not just when the fax or qt4 use flag is used. PyQt[dbus] depends on dbus-python, so all users with the qt4 use flag on hplip will have dbus-python installed. Those few of use that do not have the qt4 use flag set may not have dbus-python installed. My experience has shown that hp-setup will not work without it, but is doesn't abort on the error, so the user may think that hp-setup worked. Later printing will not work. In this case, installing dbus-python and rerunning hp-setup will fix the problem. Installing PyQt[dbus] and running hp-setup will have the same effect since PyQt[dbus] requires dbus-python.
Paweł is it possible that your problems are plugin related like Marathon reported? I see you own a HP LaserJet 1022 and this printer needs a plugin. At least a plugin for your model is listed here [1]. [1] http://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/
Paweł any news on this? Especially to comment #7
(In reply to comment #7) > Paweł is it possible that your problems are plugin related like Marathon > reported? I was using hp-setup. I'm not sure if that was downloading a plugin behind the scenes. Note that the main problem is that the issue is intermittent. Anyway, I'm no longer using the HP printer with that box, so can't really test it anymore. Feel free to close as WORKSFORME.

Normally you should recognize when a plugin is downloaded. It looks like you are the only one having this problem, so I will close this bug for now. Lets see if this issue pops up again. Thank you for the feedback.
