I am using HP LaserJet P1005, as maybe someone of you know, this printer doesn't work with the default drivers, so i downloaded and installed hplip, and everything worked fine for a day and then it stopped working. I wasn't able to discover what the problem is so i decided to remove the hplip package and install it once again.
So I installed F17 on my Lenovo Y550 yesterday, and tried to setup the printer today. The printer is an HP LaserJet P1102w, which should be supported by hplip. After downloading hplip and installing it, however, the hp-setup application can't detect my printer even though it's connected by a USB (and I've tried all 3 ports, the problem doesn't seem to be with the USB's themselves).
Thank you for your help.I run hp-doctor, which reported a wrong plugin version.So, I reinstalled the plugin (please note that the downloader needs /usr/bin/python to point to python2!), and now the printer works with the current version of hplip.Solved!
