Recently tried hplip 3.14.10. After installing it and when I pushed "Add Printer" button in HP-Setup a 'Firmware download failed' windows appeared. Then I started 'Diagnose HPLIP Driver' from HP Device Manager's 'Device' menu and got the following results:

I restarted the printer, tried to refresh device in HP Device Manager but in terminal still following:

warning: Supplies information not available for this device.
error: Unable to communicate with device (code=12): hp:/usb/HP_LaserJet_1018?serial=KP39HE7
error: Device not found

I launched hp-check. Please, see: hp-check.prev
I reboot my system and then also restart the printer.

And the interesting thing is that if I completely remove HPLIP and install lj1018 with Foomatic driver IT WORKS WELL although device descriptor read error messages.
