Excel 2007: Printing Settings Ignored on Multiple PCs Using Same Workbook

I Work in a Computer Center that has three PCs with Microsoft Office 2007. We daily print out our production itineraries, but lately we have to use one PC because the other two PCs print settings go out of order, even though it's the same workbook and the same path. I have checked the settings from each PC and everything looks the same, but the print settings continue failing. (Example: Sheet1 has a single page and when we use the other PCs to print the same worksheet, print two pages.)
