Terminal Services Printing

I have loaded the same driver for a lexmark25-35 printer but the darn thing still won’t print via terminal services. I am at W2k SP3 and 100% update on patches. It sets the printer up but nothing happens. The client is xp, the printer usb, and the server is Windows 2000. Any ideas? Also, I can only install the windows 2000 driver on the server. Does the print use the xp driver or the w2k driver? Should they be the same?
