The problem computer is running Firefox 51. Nothing has been printed in past weeks ... so we don't know when the problem happened. But today the attempt to print the page results in oversized font being displayed within the normal sized html table borders. At the same time, the large monitor (which is connected as a 2nd monitor to a laptop) may also be displaying larger font -- with an occasional messing up of our intranet site's web page. Zoom was reset. The basic page style option was already selected. The css for html has this font instruction: font-family:Arial, Helvetica, sans-serif; Then the body specifies: font-size: .8em When trying to print , the "Shrink to fit Page size" option is selected. The font appears to be 40% too big. (this is a problem on a windows 7 laptop. I didn't get to try SAFE mode on that computer.)
