Hi Bernhard,

I understand that.

Well... I just checked the content of the cups-bsd package and it  
seems absolutely unrelated to X2Go's client-side printing mech.

The only thing that might be relevant is the list of dependencies:

"""
libc6 (>= 2.4), libcups2 (>= 1.4.0), debconf (>= 0.5) | debconf-2.0,  
cups-client (= 1.5.3-5+deb7u4), update-inetd, cups-common
""" -> on Debian jessie

Could you check /var/log/dpkg.log for other packages that got pulled  
in with the installation of cups-bsd? If you are right that a package  
has been missing, we need to add it as a dependency for cups-x2go  
and/or x2goserver-printing.

In the above log message I count command (x2goprint) plus four  
arguments, right?

The code that triggers the error message is this:

	elsif (scalar(@ARGV) != 4)
	{
		syslog('err', "ERROR: x2goprint was called with a wrong number of  
cmd line args, x2goprint exits now!");
		print { \*STDERR } "ERROR: Usage:\nx2goprint user session file  
titleFile\nx2goprint user\n";
		exit 1;
	}

I see that not x2goprint is called, but x2goprint.orig. Did you change  
anything in that script? Did you use a wrapper?

Please get everything back in place and use the default installation  
of x2goserver-printing for testing or fix the test setup (the wrapper  
script you use).

You can also enable debugging for x2goserver-printing in  
/etc/x2go/x2goserver.conf. That should show you how x2goprint(.orig)  
gets launched, including the used cmdline options.

Mike
