I don't see why you say
The document needs to be in PDF format from the start. Why can you not print directly to your printer from the email?
I have an AOL email the text of which I want to convert to a PDF document, using a PDF-handling program, such as PDf Creator / PDFlite / NitroPDF. As you imply, I can, of course, send it directly to the printer, but I don't want that; I want it in PDF form.
