"Open print channel failed"

[Paul van der Vlis]

Hello,

After update of Debian from 3.1 to 4.0 I have a printer problem at a
customer. Cups says: "open print channel failed; will retry in 30
seconds...". My customer has an HP laserjet 2300d, connected with USB.
They are using HPlip. In syslog I see: "hpiod: invalid MLCInitReply".

I will attach what "hp-info" says, and some data from
/var/log/cups/error_log and /var/log/syslog.

What will be wrong, is this a hardware problem?

With regards,
Paul van der Vlis.
