I was greeted with this message in my Samsung ML-2851ND Laser printer panel when I tried to print wirelessly from my DELL WinXPsp3 laptop. I can print to my other two inkjet printers on the same network with no problems. I repaired the Samsung driver installation in Add/Remove Software, uninstalled and reinstalled Samsung drivers and software, tried system restore in safe mode,and in regular mode. I also tried stopping and starting the print spooler service in services misc. In addition,I tried deleting and recreating TCP/IP printer ports and I turned off the firewall in NIS 2009. All these attempts did not work. This networked printer worked flawlessly for over one year. Any help will be greatly appreciated. Thanks.
I am using a Linksys WRT54GS G router and the IP address of the printer is 192.168.1.102. The Samsung Syncthru configuration page at that address is also not accessible anymore.
