CUPS Printer Stalls at "Sending Data to Printer"

Question

This is related to a previous problem, though the problem has changed significantly so, I have opened a new thread.

I'm trying to set up a Cannon iP4850 with Cups (for my Raspberry Pi) running on Debian.

I've got cups installed, then compiled the drivers for the Cannon taken from http://software.canon-europe.com/products/0010893.asp

The drivers came in two parts the PPD (compiled and Cups picks up) and 'pstocanonij' with converts postscript to work with the printer (I assume).

However the printer now just stalls at: Idle - "Sending data to printer." whenever trying to print on it. I've set the log level to warn and there doesn't appear to be anything related showing up (I'm using print test page).

Error Log:

E [09/Sep/2012:15:26:29 +0000] Unable to open listen socket for address [v1.::]:631 - Address family not supported by protocol.
E [09/Sep/2012:18:50:06 +0000] SSL shutdown failed: Error in the push function.

Printer Info:

Description:    Canon iP4800 series
Location:   Lounge
Driver: Canon iP4800 series Ver.3.40 (color, 2-sided printing)
Connection: usb://Canon/iP4800%20series?serial=2239B2
Defaults:   job-sheets=none, none media=iso_a4_210x297mm sides=one-sided

Does anyone know why this is happening or what further debug info I can provide?

Answer 1

In the error log it is trying to bind to an IPv6 address. You should check in cupsd.conf that Listen ipaddress:port is set to the local IPv4 address of the raspberry pi. It's likely that cupsd isn't even starting up because it's failing to bind to a port.

Answer 2

Make sure that /etc/cups/cupsd.conf allows incoming connections from your local network by inserting a Allow from <NETWORK-PART>.*

here are are parts where I inserted the lines from my config file

#Restrict access to the server...
<Location />
Order allow,deny
Allow from 10.0.0.*
</Location>

#Restrict access to the admin pages...
<Location /admin>
Order allow,deny
Allow from 10.0.0.*
</Location>

# Restrict access to configuration files...
<Location /admin/conf>
AuthType Default
Require user @SYSTEM
Order allow,deny
Allow from 10.0.0.*
</Location>

According to your comment you still have problems with a line like Listen 192.168.0.5:631 ... - are you sure you have restarted your cupsd with sudo service restart cups?

• Do you still have the Listen /var/run/cups/cups.sock line afterwards? Without that it won't listen to incoming network connections at all I suppose.

• have you commented all other similar Listen lines like the following ... cups will only process the first one it finds.

I had these error logs with following possibilities, my cups version is 1.5.3, kernel 3.18.11+, debian_version 7.8, raspbian

• Listen 10.0.0.*:631 ... Bad Listen address 10.0.0.*:631
• Port 631 and Listen *:631 ... Unable to open listen socket for address [v1.::]:631 - Address family not supported by protocol
• Listen localhost:631 ... no error but Webinterface was not accessible anymore from remote pc.
