print problems

I really hate printers.
I have a Color Laserjet 5m - quite dead. I replaced every piece inside it - figured out the board is bad. It thinks the parts are all bad, so it won't print.
I also have a Lexmark black and white laser - didn't work for quite awhile, just because the toner costs more than the printer. I finally found some toner on ebay for it, so it's back and happy.
Printer 3 is an HP officejet all-in-one - quite dead. If you plug it into any computer, it murders that computer. Shuts it down without blinking.
I just bought a new HP inkjet today, because...
I decided to be clever and printed up some color letterhead on an oki laser at my former office. I thought i'd then print out the black and white stuff at home at my leisure. Oki uses a wax based toner tho... so when you run it thru a laser again... it melts the letterhead.
yeah, so i hate printers.
