Comment 54 for bug 329898

After hplip-3.14.6 was installed printer worked well. Then I connected another one - HP DeskJet 2050. And it also automatically worked well. But after I rebooted my system LJ1018 again could not print test page. Hp-check was runed and you can see their output in attachment. HPLIP icon in tray also from time-to-time says:

HP_LaserJet_1018 Printer (KP39HE7) Device communication error (5012).
