The history of the ABXPDF Writer

The ABXPDFwriter which is part of the August 22, 2004 release of EFS is basically the free software called CutePDF writer which has been around for many years.

The ABXPDFwriter writer was probably created using the Custom PDF creator from Acro Software (the people who distribute the free CutePDF writer). This custom package describes itself as "the easiest and most affordable way to have your own PDF writer. ROYALTY FREE! Just purchase the custom package once, and you're free to use or distribute it however you want. ... effortlessly offer your customers a PDF writer with your own title." The purchase price for this package is $400. So I expect it will be possible to learn quite a lot about the ABXPDFwriter by studying the documentation for CutePDF writer.
