What distro are you using???

The file permissions of /usr/lib/cups/backends/cups-x2go should be  
0700:root:root. Is that the case? CUPS will execute a backend with  
that permissions with root privileges. If the privs are different, the  
backend will run as user lp:lp, which will not work as x2goprint uses  
the su command and expects root privileges.

Note: if you run CUPS and X2Go Server on a different machine, then  
cups-x2go has to be installed on the CUPS machine and  
x2goserver-printing is needed on X2Go Server(s). For multi-host  
printing, you also need a line in /etc/sudoers (that should be on the  
wiki somewhere).
