I have a Lexmark X4850 hooked up via wifi to my Linksys WRT54GL. The printer installs onto the network fine. I load the drivers onto my mac laptop and my windows xp pc. Everything works fine....at first. After a few days to a week i will go and try to print and it says printer is not connected or turned on. Which is not correct because when I check in my router it still shows it connected and the wifi light on the front of the printer is still green. The only way to be able to print is to either re-install the printer drivers or unplug and reset the printer, which requires it to do a alignment and waste more ink...is there anyone else having this problem and is there anyway to solve this issue??
