If you are getting crooked prints from your printer, the solution might be as simple as replacing your toner cartridge. I was using a refurb toner cart in my HP LaserJet 1200 and thought the fuser was bad - I went so far as replacing it, before I realized that my almost-new toner cartridge was to blame.

Page skew is when the image and text on your paper is rotated or crooked. On mine, the top right corner of printing was off the page, while the top right corner looked ok. The whole print was rotated counter-clockwise.
