Hi Carl,
welcome aboard
I see there is a new Vista driver out for this printer @
SAMSUNG's Digital World - Support
It is dated 14th November 2007. The first thing to do would be to make sure you have this latest driver.
Install the driver on your Windows Vista computer. During installation, you’ll be prompted to connect the printer to your computer. Choose the option to proceed with installation without connecting the printer.
After installation completes, open the Printers applet from the Windows Vista Control Panel.
Right-click on the new Samsunh ML-2510 Series printer and choose Properties.
Go to the Ports tab.
Click Add Port…, select Local Port, then click New Port…
For the port name, enter exactly the network path and share name of your printer \\UPBEAST\SamsungM
Click OK, and double-check that this new port is selected with the checkbox next to it.
Click OK to close the printer properties
Hopefully this will do it.
regards
Steve
