Excel 2007 Gridlines Not Being Printed Out

I am using Excel 2007, and its been updated to the most recent version. I have a problem where i one or two times, i will get to print gridlines for all the boxes, but then all of a sudden it refuses to print them. I have the sheet options checked, and in the print preview screen they show up. When its printed there are no lines only text. If i create a new spreadsheet it works, but then after a couple times it messes up again.

 

I will look into this, but I suspect this is a known issue with some print driver conversions.

Please let me know the printer and the driver version.

Have you downloaded the most recent driver (is this running on Vista or XP)?
