have you installed the printer on the pc ?
• Click Start and then click Control Panel.
• Click Printers and Other Hardware, and then click Printers and Faxes.
• In the Printers and Faxes folder, I clicked the printer's icon and, in the tasks pane, I clicked Share This Printer.
• I opened the printer's Properties dialog box, and clicked on the Sharing tab.
• I clicked Share Name, and then clicked OK.
That's it—the printer was immediately available for other computers to use.
Now that I had a network printer, I was ready to connect to it and print from other computers on the network.
To connect to the printer
• I opened Control Panel, and clicked Printers and Other Hardware.
• I clicked Add a Printer.
• Instead of adding a local printer, though, I clicked Printer Connection and then browsed the network for the printer.
