Make sure that you do not have any scaling options enabled when printing or have the incorrect paper size selected.
Once you bring the report up to print, on the “Print” screen, try the following:
Under “Print Range” don’t check “Current View” leave it at “All”
Under “Page Handling” change the Page Scaling to “None”
And, then further under “Page Handling” UNCHECK “Auto-Rotate and Center” See Optimize Your Browser: Printing
For Acrobat Reader X and above: set Size Options = Actual Size. There is no "Page Handling" feature.
