I have an HP psc 1350 printer on a D-Link DPR1260 print server and it works with Vista and XP, but I can't get it to work with Windows 7 RC. I've gotten it to detect the printer (had to connect directly to the printer to get drivers installed), yet it doesn't print.
Is the printer still connected to this Win 7 Computer and what type of interface cable? Ethernet or USB?
Did you Power Off and Power ON the Printer and Restart Computer after installing the driver?
