"Note to self: Do not make any changes if you have not slept for two days!!"
Looks like you've set your paper size to 444 x 14994 mm (about a half meter by 15 meters or 17 inches x 49 feet)! When you do your printer setup in the unclog dialog (setup button), give it a more reasonable page size such as the suggested letter or A4 size and the problem should go away.
