Titolo: CentOS 6 e cups che non mi vede la stampante

Ciao a tutti, ho una stampante usb epson d92 che è connessa ad un router 
casalingo, il quale funge anche da print server. La connessione alla 
stampante avviene impostando il link 
"socket://ip_router:9100/printers/g3672b". All'interno della mia rete ho 
tre pc (un notebook e due fissi), dove due riconoscono correttamente la 
stampante (sul portatile c'è fedora 17 e su uno dei due fissi bodhi 
linux), mentre sul terzo che ospita CentOS 6, le stampe non riescono a 
andare a buon fine.
 
Tengo a precisare che sul sistema è stato disabilitato il servizio 
selinux e il firewall e sniffando il traffico mediante iptraf, il 
traffico tra il pc e il router avviene sulla porta corretta ma si 
interrompe immediatamente restituendo poi nei log l'errore.
 
Anche riuscendo a catturare i messaggi di errore non sono riuscito a 
venirne a capo e con il vostro permesso e scusandomi per la lunghezza 
del copia incolla, vi incollo il risultato del comando "tail -f 
/var/log/messages";

Il problema del capitalismo è che il padrone è troppo ingordo..

 Ciao a tutti, ho una stampante usb epson d92 che ï¿œ connessa ad un router
[cut]
 
Potete ignorare il post. Mi hanno risposto dal forum CentOS italia che 
trattasi di bug del driver (e difatti con il suo omonimo ma marcato 
"simplified" funziona).
 
Ora mi studio come funziona abrtd e manderï¿œ segnalazione a chi di dovere.
 
Saluti, Davide.
