I spent nearly an hour today trying to get my house's printer working right. No matter what I did the damn thing just didn't work...at all. It wouldn't even recognize that I had plugged it into a computer. I was like, "Okay, what gives? It should at least give me some feedback, an error message or something." I tried many times, over and over, but still no dice. I figured it had to be something simple that I had overlooked. I turn the printer in every direction looking for small switches or buttons that might give me a clue as to what was amiss.
Nothing.
I figured it was time to give up. I pulled the USB cable out of my computer, and ran my hand down it on the way to the back of the printer. During my hand's journey it encountered something most peculiar. I pulled the cable from behind the desk and was greeted by the following sight:

Yep. The cord was F.U.B.A.R. Completely and utterly. I replaced the cable with a spare I had lying around, and got the whole deal working perfectly in less than a minute. As a matter of fact I used it to scan the above image.
It figures.
