Hallo Guys! I would like to ask if anyone managed to get client-side printing work on an ubuntu 14.04 powered x2go server. On my installation everything seems fine. In the syslog i can only find one error message, that x2go print could not process the print file.

Mayr
first thing: don't use X2Go as root on the remote X2Go Server. Please avoid it if possible.
second: your issue seems unrelated to #702 (mentioned by Stefan)third: x2goserver-printing and cups-x2go are working fine between two Debian jessie systems (and also other combinations), so I suppose there is a setup issue.
fourth: http://code.x2go.org/gitweb?p=x2goserver.git;a=blob;f=x2goserver-printing/bin/x2goprint;h=c24975e4e6c7e769eacf88e5689fb5ef1f333704;hb=91da54c9f1c64dd62fd311735c9d09219208e68b#l115 This is where your error occurs. The problem is that the print files cannot be copied to the sshfs-mounted print spool mount point at /tmp/.x2go-$user/spool/tmp/ ($spooltmp).
We have received reports where someone says that CUPS remounts /tmp on processing print jobs. I could not confirm that with my running setups. However, I hope this gives you some help in debugging and tracking down the issue.
Digging deeper... The cups.service file for CUPS in Debian jessie is this: """ [Unit] Description=CUPS Printing Service Documentation=man:cupsd(8) man:cupsd.conf(5) Requires=cups.socket [Service] ExecStart=/usr/sbin/cupsd -f PrivateTmp=true [Install] Also=cups.socket cups.path WantedBy=printer.target """ -> Maybe the PrivateTmp causes your issue...
