Xsane: Не удалось открыть устройство 'hpaio:/net/Photosmart_C5100_series? zc=HP5180': Ошибка во время устройства ввод-вывод

Печать из приложения работает. Hp-панель-инструментов иногда не может соединяться. И Xsane выталкивает сообщение об ошибке как в заголовке. Соединенный через сеть, я могу проверить с помощью ping-запросов устройство, я могу распечатать к нему.

Единое раньше хорошо работало только что (по крайней мере, прежде 12.04).

Вывод hp-check -rt следующие:

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz 
or .run) to determine if the proper dependencies are installed to successfully compile HPLIP.                    
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc)  
or an already built HPLIP supplied tarball has the proper dependencies installed to successfully run.            
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases  
(both compile- and run-time dependencies).
