I'd say that depends on your usage scenario. If you're running VPN 
connections or dedicated lines between several WAN sites (I'm assuming 
there's no need for traffic shaping within a LAN), then nothing forces 
you to use x2go's built-in file and print sharing.

In my particular use case, printing is done by CUPS connecting directly 
to ports 515 and 9100:
- 515 for LPD on *nix and Windows (yes, Windows has an LPD server as 
well) and older network-attached printers,
- 9100 for TCP/IP-socket-printing on newer network-attached printers.

Of course, if you're using x2go's SSH connection to avoid a full-blown 
VPN, that's not going to help you.

It *might* be possible to do throttling on the server side using some 
iptables magic, but I've never tried that.
