Excel Printing in Half Pages

I've been struggling with this for a while. I think this is an issue with both Excel and my printer.

I have a workbook with 30 different worksheets that are all the same. There are 20 columns wide and set at a print area of 1 page by 1 page. Some of the worksheets print great, but for others I get a page that prints the second half of the columns (K through T).

When I email the document to another computer, it prints just fine.

Because I am getting some worksheets to print just fine, I have to think there is a setting in Excel that is throwing off the other worksheets, but that is just speculation.

Please help!

Thanks for the response! I tried to clear theprint area, but it didn't seem to fix anything. However, I will say that I suddenly realized that some of the work sheets had the print quality drop down left blank while the others were at 600 dpi. I changed them all to 600 dpi and I haven't had a problem yet.
