You don't need Acrobat Pro. Install CutePDF - you can get it
here.
Warning, some software on this site require that adware stuff to work properly, but the basic CutePDF does not! At least this company is up front enough to tell you they are installing it when you install their software!
Do your stuff in DIP and set it up like you normally would to print. Then go to print. When your print dialog comes up you have a new printer installed 'CutePDF' . Choose this, print, give it a file name and done...
Be warned, just because it is in a PDF format does not mean it is free from other people tinkering. Anyone with Acrobat Pro, possibly other programs, can pull it apart and get your image back out....
