This bug is old so lets renew this a bit with my experience on Ubuntu Mate 16.04... I have a HP LaserJet P1102w
Installation detected the printer on the network and everything seemed fine until i tried printing, it did not work. i new i needed to run hp-plugin at this point but there was no information or any specific error pointing me to it. Running hp-plugin failed with it complaining about a missing gui library of some kind. After installing hplip-gui, running hp-plugin as a normal user went smootly. It asked for my password and installed fine. The printer was working after that. There is a feature request for the missing hplip-gui... https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/802304 Sorry not sure if i should close this bug or not... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/913730 Title: Automatic plug-in installation not working under Ubuntu Status in HPLIP: Invalid Status in hplip package in Ubuntu: Triaged Status in policykit package in Ubuntu: Confirmed Bug description: I have packaged HPLIP 3.11.12 for Ubuntu Precise (12.04) and I have also backported this package to Oneiric (11.10, package in my PPA: https://launchpad.net/~till-kamppeter/+archive/ppa). With the binary package hplip-gui and all its dependencies installed the plug-in should be downloaded and installed automatically if a printer gets connected which requires the plug-in, via the newly added feature of HPLIP 3.11.12. It seems that when hp-systray calls hp-plugin, hp-plugin gets run as normal user (not as root) and then it is not able to install the files of the plug-in in subdirectories of /usr/share/hplip and /etc where only root has write access. What needs to be done here is to use PolicyKit or tools like gksudo. Is such a thing actually used?
