Printing Excel 2004 Worksheets to PDF in Panther

[nhop]

I'm using Mac OS 10.3.9 and Excel 2004. I have an Excel spreadsheet with multiple worksheets. When I try to print the entire workbook to a single PDF file (I'm doing this from within Excel via File --> Print), only the last worksheet gets saved to the PDF file.

I am trying to do the same thing with another, similar Excel spreadsheet, and only the last 2 worksheets are in the PDF file.

I am sure that I am telling Excel to print the entire workbook.

My printer selection is set to the printer that I normally use - a networked HP LaserJet 4M Plus.
What am I doing wrong?

Thanks.

Nancy.
