Excel files on XP Won't Fully Print

I have uninstalled and reinstalled and still have the same problem. Granted the excel files are old and have many tabs. All of the tabs print fine on a regular printer. But in converting to a pdf format, some do just fine from the file. Others in the same file will only print about 60% of the page and nothing more. I've created new tabs and copied the old tab into the new one and the print comes out fine. But this is very time consuming for a ton of files/tabs. I've tried clearing the print area in the original tab and recreating the print area, to no avail.

Any idea what I can do? Thanks!
