tsclient is a front end for rdesktop and VNC, made to look like the
Remote Desktop Connection you find on windows. Make sure you have the
printer mapping option checked in tsclient. If that doesn't do it,
open a terminal and try:

# export PRINTER=printername
# tsclient &

And if that doesn't do it, my last guess is that you need to setup
your printer under samba.

Or you could Read The Fine Manual. :)
