printing ? instead of bullets

Sounds like a fonts substitution issue. Generally this should not happen with PDF documents.

You might want to re-install Windows on top of your current installation (if Win9x). You you may want to look at the printer setup and see if there are additional fonts built into the printer software. (I have never used any Cannon, so I do not know anything about them).

This is a printer driver problem. Locate and install the exact driver for your printer model and operating system. Also pdf files, I am almost sure, require postscript driver. If you have the installation disk for the printer you are in luck if not go to the Cannon site and download it. The correct driver solves this problem.

Get the correct postscript driver from the installation disk or from the manufacturers web site. Get the postscript printer definition file (PPD) for your printer from Adobe. Once these are set up you should be able to print OK.

This is not a print driver or printer related issue. This is an Acrobat related issue. Any documents transferred into a .pdf format by a version of Acrobat Exchange later than 5.0 will graphically display all bullets as question marks in Acrobat Readers. This issue has been resolved in Acrobat 5.0. The original document will need to be transferred back into a .pdf file using Acrobat Exchange 5.0
