We are having the opposite problem; our pages display correctly in "real IE8" (or IE9) mode, but we have been having continual problems at a customer site where they report the printed page is shrunken when "shrink to fit" is set; so I have now tried running the site with "compatibility mode" turned on, and I see the pages being shrunken as well.
We've been over the site with a pretty fine toothed comb and there seems to be no reason for the pages to shrink, they are well within a standard page width.
This gives us a handle on what the problem is, and if others are experiencing shrinkage problems, maybe getting OUT of compatibility mode is the answer.
I am experiencing this as well. Strange part is that if you change orientation to landscape and then back to portrait in the print preview window, it shrinks to fit perfectly. Very frustrating. – Josh Stodola – 2011-12-22T13:11:18.603
I know it's not a solution, but what if you try to print your file into a PDF printer ? Is the right side still missing ? I'm not sure how printers works with windows, but maybe the printer is incapable of this. If it prints well into PDF, then try to print the PDF itself. (This way we'll know if the problem comes from Windows or the printer itself.) – PatrickCUDO – 2011-12-27T17:40:43.347
@PatrickCUDO yes printing to PDF or XPS file both result in the same truncation – Josh Stodola – 2011-12-29T06:04:43.677
