I just had the same problem on a default Ubuntu 13.10 install. I have an HP LaserJet P1102 that worked on Ubuntu 12.10.
On 13.10 the test page would print but no applications would print. The job would be stuck in the queue. After unplugging and plugging the printer a few times with no success, I ran a tail on syslog while I plugged it in again. See attached 1-printer_syslog.txt Searching on /var/lib/hp/hplip.state I found bug 1018303. The directory already existed, so I tried running hp-plugin as root and accepted the driver license. The printer now works. What is the reason for this change ? ** Attachment added: "1-printer_syslog.txt" https://bugs.launchpad.net/ubuntu/+source/policykit/+bug/913730/+attachment/3925116/+files/1-printer_syslog.txt -- 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 HP Linux Imaging and Printing: 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?
