Ever thrown a printer across the room and heard it slam to the ground, crushing the internal parts into useless plastic shards? I had never known that experience until yesterday.*
After clicking "OK" for the 40th time because the black cartridge was empty, and reprinting a check to the federal government (which was due in 30 minutes) a handful of times because the printer couldn't understand that the paper WAS, in actuality, inserted correctly... I blew a small gasket.
Pulling the power cord from the wall (and that's all because it was a wireless printer) I picked up the printer, turned toward the door and heaved it into the family room outside of my office.
"CRASH!!!!!" At the same time it felt great and horrible.

I made out the check by hand, got to the bank with 45 seconds left, then went to
Office Depot and bought a new printer. (it's such a new model, it's not even on their website yet - they had just gotten it in that day) I'll never go back to HP printers again - I'm a Brother man now.
The new printer is quite large and very heavy - therefore not throwable.
And now the fine print - I'm not proud of losing my temper. I haven't been that mad in a long time, and it was the culmination of several events during the day that stacked up over time. I hate waste. It was an okay printer and was only 8 or 9 months old, but it seemed crazy to allow a piece of equipment to stand in the way of productivity. I figured since it wasn't working I needed to replace it... but I feel pretty stupid for having thrown it.
