Excel 2007 lower case o (Oh) print issue
 

I have an Excel 2007 spreadsheet that uses lower case o's (Oh) in some cells
that show in print preview but do appear on the printed document. The
document is printed on a HP 4600 color laser. I can print the same document
to the same HP4600 from a different PC with Excel 2003 and the o's print as
expected. I have verified that both PC's are using the same print driver and
both PC's are XP Pro machines. I've applied all updates to the Office 2007
machine with no change. Any suggestions?
