[SLACK]problema con la configurazione della stampante [RISOLTO]

[jnsen]

Ho una stampante Epson Stylus Photo 810, perfettamente compatibile secondo linuxprinting.org. Ho fatto la configurazione tramite web (http://localhost:631) e ho preparato diverse stampanti a seconda dell'utilizzo (testo, immagini, foto, ecc.). Provando a stampare la pagina di prova da web la stampa avviene senza problemi, ma quando provo a stampare da riga di comando la stampante non funziona e questo è l'output su console:

Status Information, attempt 1 of 3:
sending job 'root@darkstar+522' to testo@localhost
 connecting to 'localhost', attempt 1
 cannot open connection to localhost - No such file or directory
Make sure the remote host supports the LPD protocol
Waiting 10 seconds before retry
Status Information, attempt 2 of 3:
sending job 'root@darkstar+522' to testo@localhost
 connecting to 'localhost', attempt 1
 cannot open connection to localhost - No such file or directory
Make sure the remote host supports the LPD protocol
Waiting 10 seconds before retry
sending job 'root@darkstar+522' to testo@localhost
 connecting to 'localhost', attempt 1
 cannot open connection to localhost - No such file or directory
Make sure the remote host supports the LPD protocol

sapete dove sta il problema?

[parsEc]

CUPS o lprng?
USB o su Porta Parallela?

Che comando dai per stampare da riga di comando?

[jnsen]

Uso Cups 1.1, ma nel sistema ho installato anche lprng. la stampante è USB su /dev/usb/lp0
il comando è questo:

lpr -P testo prova.txt

dove "testo" è il nome che ho dato alla stampante (intesa come modo di stampa) nella configurazione web e prova.txt un file di testo nella stessa cartella da dove do il comando.

[parsEc]

Edita il file /etc/cups/cupsd.conf e metti debug2 al livello di log

LogLevel debug2

riavvia il server cupsd

/etc/rc.d/rc.cups restart

Quindi fai un'altra prova (che sicuramente fallira') e posta il log della "sessione":

/var/log/cups/error_log

(ovviamente solo quello riguardante questa prova... controlla l'orario nel log)

PS
Posta il contenuto di /etc/hosts

[jnsen]

questo è il log della sessione, tutte le linee tranne le ultime due in realtà sono del riavvio di cups. solo le ultime due si riferiscono alla stampa.

...e questo è il mio /etc/hosts:

#
# hosts		This file describes a number of hostname-to-address

#		"named" name server.  Just add the names, addresses
#		and any aliases to this file...

# By the way, Arnt Gulbrandsen <agulbra@nvg.unit.no> says that 127.0.0.1

# For loopbacking.
127.0.0.1	localhost
# This next entry is technically wrong, but good enough to get TCP/IP apps

ps: scusa per il ritardo nella risposta ma ho dovuto reinstallare slack perchè ho fatto dei casini nella ricompilazione del kernel...

[jnsen]

scusa, mi sono sbagliato, in realtà credevo di usare cups, ma stavo usando lprng.
a questo punto cosa devo fare per dire al sistema di usare cups invece che lprng?

ps: ho slackware10

[parsEc]

Ma hai installato anche cups?

Ricordo che quando metti entrambi i sistemi di stampa vengono adottate delle contromisure per evitare conflitti... fai in questo modo e vai sul sicuro (spero)

removepkg lprng cups

Quindi installa nuovamente cups... e fai le dovute prove.

[jnsen]

Tutto sistemato!
Il problema evidentemente era il conflitto fra i due pacchetti. Ora ho installato solo cups e tutto funziona.
grazie
