Recentement he comprovat una cosa curiosa en l’ordinador d’un amic.
El seu Ubuntu Breezy tenia ben detectada, ben configurada i ben connectada la seua impressora HP 710C però no imprimia res. Com llegiu. Fins i tot vaig comprovar a linuxprinting.org que el connector que fa servir Ubuntu és el correcte.
Com podia ser això?

Un poc de cerca per Internet, què gran invent!, i de seguida vaig trobar on estava l’errada.
Cal modificar la següent línia del fitxer de configuració del connector /etc/pnm2ppa.conf:

# Sample configuration file
#
# This file will be automatically read upon startup if it is placed in
# /etc/pnm2ppa.conf
#
# uncomment entries by removing “#” to activate them.
#
#———–set the printer model—————————
# The printer model will normally be set by a -v command
# line argument. Otherwise, if not set in the configuration file
# it defaults to the 710/720 series. Remove/comment out the line
# “version 0″ below to get the default choice.
#
# If there is more than one “version” entry activated, the last one
# will be used. The printer version can also be set with the command line
# option e.g., “-v 720″.

version
#version 720 # 710, 712, 722 also acceptable
#version 820
#version 1000

per aquesta que és la correcta:

# Sample configuration file
#
# This file will be automatically read upon startup if it is placed in
# /etc/pnm2ppa.conf
#
# uncomment entries by removing “#” to activate them.
#
#———–set the printer model—————————
# The printer model will normally be set by a -v command
# line argument. Otherwise, if not set in the configuration file
# it defaults to the 710/720 series. Remove/comment out the line
# “version 0″ below to get the default choice.
#
# If there is more than one “version” entry activated, the last one
# will be used. The printer version can also be set with the command line
# option e.g., “-v 720″.

version 710
#version 720 # 710, 712, 722 also acceptable
#version 820
#version 1000

I ja està!!
Ho penge per si algú ho necessita en algun moment.
