We go through a LOT of paper and toner here in the Dick Smith Library. It can be frustrating when a large job is previewed before printing, and it shows a single line on the last page.
Did you know there's an easy way to eliminate that problem with Word documents? From within the Print Preview window, click the Shrink to Fit (Word 2003) or Shrink One Page button (Word 2007). Word will tweak the fonts in the document to make it a page smaller. If you don't like the results, just press Ctrl-Z or the Undo arrow (in the top upper left corner) to revert to the previous.
