I have an HP Deskjet 5440 almost brand new. I dropped a cardboard tube on it one day and now it prints out but instead of printing nicely it is stacked up.
Example, before it would print like this:

John Smith
2244 Mulberry Street
Los Angeles, Calfornia.

Now everything prints:

John Smith
2244 Mul
berry Stree
t Los Angele
s, California
