I accomplish this by having downloaded a free PDF Creator application.
use a couple different ones; each works equally well:
PDF995 --
http://www.pdf995.com/download.html
PDFCreator --
http://pdfcreator.com/
In either case follow link to FREE DOWNLOAD
This application, when installed, will appear as a printer in you
printer list. When you scan a document (or print a document from file
you select the PDFCreator (or PDF995) as though it were a printer. A
this end of the "conversion" process, you are given the option o
naming the new file and sending to a folder of choice where it will b
filed as a PDF file and from which it can be subsequently printed o
sent as an email attachment. Good luck
