I have created a workbook with 19 identically formatted worksheets in it. Each worksheet appears on-screen printing neatly on 3 sheets of paper as desired. This formatting appears consistently in all views while I am working on it and in the print preview. However, when I go to print the entire workbook, only the first worksheet keeps that formatting. Worksheets 2-19 get much larger and no longer print neatly onto 3 sheets of paper each. If I print each one individually, the formatting remains correct and everything is fine. I have checked my page breaks, my scaling percentage, my margins, that everything is centered appropriately, and have reset each one of these things on every worksheet and saved the settings. Likewise, the problem also occurs when printing a single worksheet with multiple pages. If only one copy is printed, the whole thing maintains its formatting. If more than one copy is printed, all of the formatting changes forcing it onto many more pages than appearing on-screen. Others in my office with Excel2010 are experiencing the same problem; nobody has been able to figure out a solution. Those using Excel 2007 can print the same documents with no problems at all. Is there a setting I am missing somewhere that needs to be changed?
