2. Try to print a page.

– If the printing problems persists, then continue to the next method.

– If the print output is OK,  then probably a Firefox extension (add-on) causes the print problem. At this case, disable one-by-one the installed Add-ons and then close and start Firefox normally, until you find out which plugin causes the problem.
