Like some other posts, most of which are older, my printer is losing connection. I can install the printer (Brother 2040, using the 2060 driver) it tests good. Later, or after a reboot, the printer still shows in Control Panel but I cannot print to it. If I delete it and reinstall it works fine, for awhile or until a reboot.
My printer is connected to an XP box (cable can reach where the printer has to go in the office setup) and the XP box is on my wireless network. I do have the Samba shares set up and the printer worked fine under 2009.2 KDE4.
One thing has changed on the setup, I had to change out my wireless router, could that effect this problem? I had a D-Link DIR 615, in fact still have it, but it has a heat problem, and replaced it with a Netgear WNR 2000.
