Read text from auto-saved documents

I've written a VB.Net application that automaticall saves PDF documents generated from Crystal Reports and uses a PDF printer to save the output to disk.  I then use iTextSharp to read the files to extract information from the documents.  When I use the standard Adobe printer I can extract the text perfectly fine, however, when using PDFCreator's printer the text looks encoded/encrypted/compressed/ect and is totally unreadable.

I've tried messing with some of the auto-save/pdf settings for the printer but nothing seems to work.  Any ideas?  and thank you for your time :)
