Printing from iOS via Raspberry Pi
Today I successfully managed to configure my Rapsberry Pi in such way, that I can print on my HP LaserJet 4100 from my iOS devices. I followed the instructions from http://rohankapoor.com/2012/06/configuring-the-raspberry-pi-as-an-airprint-server/. Be aware that for iOS 6 some adjustments need to be made, see the end of the instructions.
Besides the configuration instructions on the above mentioned page I had to enable the IPv6 privacy extensions, since cups gave me the following errors in /var/log/cups/error_log:
E [05/Jan/2013:19:23:40 +0100] Unable to open listen socket for address [v1.::1]
:631 - Address family not supported by protocol.
E [05/Jan/2013:19:24:57 +0100] Avahi client failed, closing client to allow a cl
ean restart
E [05/Jan/2013:19:26:24 +0100] Unable to open listen socket for address [v1.::1]
:631 - Address family not supported by protocol.
To configure these extensions I added the following lines to /etc/sysctl.conf:
net.ipv6.conf.default.use_tempaddr=2
net.ipv6.conf.eth0.use_tempaddr = 2
The last step was then to change the IP address to static (should not be necessary, since iOS should be able to find the printserver anyway, but one never knows…) following the instructions from http://www.penguintutor.com/blog/viewblog.php?blog=6306
German summary: Um mit meinem alten HP Laserjet 4100 vom iPad drucken zu können, habe ich einen Raspberry Pi nach einer Anleitung im Internet konfiguriert.
