Today I get home and what usually prints on a bit over half a page now takes 1 1/2 pages to print. Huge font size. What causes this? Where does this get changed? I've looked around but didn't find anything.

nerd alert :love:

i think someone was using the computer

could be a few things,

Driver - Do a print Preview and if it looks normal then its the driver
If not Settings on the printer options on the PC
View size Of the document
Are you printing web based?
Did you restart your PC?
