The Professional version of the PDF Creator or the PDF Converter have some additional features that may be useful. They are:
Encryption: This will allow you to set an owner password to dictate the level of access viewers of the PDF file such as; enable copying text, enable printing of the document, enable making modifications to the document, as well as a user password, optionally. The user-password setting will prompt the user opening the PDF for a password.
Web Optimization: This enables the simultaneous downloading and viewing of a document. It is achieved by splicing the document and is recommended for any web-based use of the PDF Converter or Creator.
Print Hardcopy: (developer version only) Developers will be able to direct the document being converted to a hardware printer. The Creator supports duplex printing but at this time the Converter does not.
NOTE: Starting version 3.0 of our products, all Developer versions are available in professional edition only.
