Why does my printer go offline in Windows?

Episode 1484 (36:54)

Jeff from Lakewood, CA
Brother MFC-J880DW

Jeff has a Brother printer, and every few hours, it loses its connection to his network and he has to sign back in. Rich says that the printer may go to sleep and if he presses the button on the printer, it wakes it up and the computer finds it again. But Jeff says he has tried it, and Windows still says it's offline. Jeff says it may also need a firmware update.
