I have a netbook loaded with Windows 7: Home Premium. I also have a x4550 Lexmark wireless printer. Whenever I try to print from my netbook, the printer starts printing and then abruptly stops. Then the Wi-Fi status icon on the printer then starts flashing orange (meaning there's connection problems with the router).
Another peculiarity is that my netbook gets disconnected from the wireless router when printing. I'm only able to print one page before it disconnects the netbook from the router.
I am able to print from any other PC except the one loaded with Windows 7. The drivers on the netbook are up to date for the printer as well.
