I've looked around on the internet and on the router page, but I couldn't find out how to enable the print server on the router I have. I am trying to connect a PSC-1410v USB printer to a DSL-2750B Router and Modem combo.
You need to set it up from the CD. If you have installed that, a D-link icon should appear in the system tray. Have a look at pg 121 in the User Manual.
