Computers can be fairly puzzling sometimes, with a big splash of annoying and often a fairly large dollop of frustrating thrown in. A case in point, my Brother HL-5370DW printer has been working perfectly with my Windows 7 desktop, connected via an ethernet cable, since the day I purchased the laser printer a couple years ago. This perfect track record, unfortunately, is now a thing of the past.
For some reason I can not fathom documents suddenly stopped printing. The printer was detected, the status light was green, but... nothing. The only clue was that when I brought up the window that shows the printer document queue, the window title read, "Brother HL-5370DW - Offline".
I wasted a better part of an hour trying to find a way to get it back "online" to no avail. Anywhoo, to get it working, again, I ended up adding a "new" printer via the control panel, reinstalling the device driver, and then deleting the "offline" printer.
Ultimately a simple and straight forward solution, except for the fact that the reason why the printer went offline to begin with is still a mystery. Hence the large annoyance and frustration.
Just another day in the computer age.
