I've been having problems making .PDF files from Microsoft Excel.
Everytime I use the "Entire Workbook" option in the print menu, CutePDF
makes separate files for each worksheet, or a combination of
worksheets.

I can't find any solutions to this on the web, but I've come up with
one:

* make sure each worksheet has the File- Page Setup- Print Quality
set to the same figure.

I don't know if this is fullproof, but it works fine for me.
