NIS 2009 - Network Printer not functioning properly

EPSON Stylus CX4800 printer does not print at all or prints very slowly after starting & after waiting for several minutes and then never finishes the print job. This is happening after installing NIS 2009.

 

The printer is a USB one and is connected to a USB Print Server (D-Link Model # DP-301U).

 

This continues to happen even after making the USB Print Server “FULL TRUST” under NIS Network view.

 

OS is Windows XP Home with all the latest updates installed.

 

What setting in NIS 2009 needs to change? What do I need to do fix this issue?
