Can't someone at Intuit come up with a "line item" <page break> that could be selected like any other item? 

After 30 years, still no way to INSERT A PAGE BREAK.  Just fuss and fuss adding blank lines to make your multi-page (mine run 6 -8 pages with dozens of paragraphs of description, and extra lines for subtotals so the invoice is clear and professional.  I laugh because every thread in the forum has at least one recommendation to "Rebuild Quickbooks" or "Repair Install or Uninstall-Reinstall" Quickbooks for something totally unrelated and could not be solved by wasting time.
