[ubuntu-it] Problemi con hplip

[Andrea Marengoni]

Mi ero illuso di avere risolto i miei problemi con hplip passando, dopo 
molte difficoltà, dalla connessione USB a quella LAN, invece ci 
risiamo... Ecco cosa succede quando da hp-toolbox (lanciato da terminale 
per scoprire l'errore) clicco su send-fax e poi su add, aggiungendo, 
come al solito (per molte volte ha funzionato) il file in formato 
postscript generato con stampa file e collocato nella cartella Fax da me 
appositamente creata (lo stesso errore si verifica usando il comando 
file - stampa e selezionando la stampante fax):

"ERROR:dbus.connection:Unable to set arguments 
('hpfax:/net/HP_LaserJet_3055?ip=192.168.1.4', 'andrea', None) according 
to signature None: <type 'exceptions.TypeError'>: Don't know how which 
D-Bus type to use to encode type "NoneType"

Cosa posso fare per risolvere questo problema? Grazie mille. Ciao e 
grazie in anticipo a chiunque mi possa aiutare (o ci provi). Andrea
