Cannot print from network printer while on terminal server

I have two (local) network printers – HP PSC 750xi & Samsung ML-1710. While connected to the remote Terminal Server I am able to print on the HP. However, when I try to print on the Samsung, the printer activates as if it's going to print and then does nothing. Anyone know what I need to do in order to print on the Samsung? Thanks.

EDIT:

The terminal server does have the appropriate drivers for both printers — in the case of the Samsung it is the "Samsung Unified Print Driver."

When I print, the printer queue takes the target document and moments later removes it as if it was successfully printed. When I check the event viewer (of the TS) there is a notice that states:

"Document owned by Dan was printed on
Samsung Universal Print Driver in
session 1 via port TS001."

But unfortunately, the printer does not actually print any document.
