-Please make sure that you are logged in as user ''root'' on the system running the CUPS service and add the following folders:+As first step: install the X2Go server printing add-on to your (every) X2Go server:
  
 +<code>
 +$ sudo aptitude install x2goserver-printing
 +</code>
 +  
 +Next, install the CUPS X2Go backend on the CUPS server:
 +
 +<code>
 +$ sudo aptitude install cups-x2go
 +</code>
 +  
 +On the CUPS server create ''root'''s SSH configuration directory:
 +  
 <code> <code>
 $ mkdir -p /root/.ssh/ $ mkdir -p /root/.ssh/
 </code> </code>
  
-Now you can generate the keys (on each X2go server that shall have access to the CUPS service):+Now you can generate an SSH public/private key. This key is used to allow passwordless logons from ''root@cupsserver'' to ''x2goprint@x2goserverX''.
