He uses the API to provide a simple viewer that has two icons: one for print and another for save. His screen shot shows how he is using the control with this minimal interface.
Software Quality Assurance Engineer, John Schmier, noted that the Commands collection returns strings that are for internal use. You should only use the strings that are documented in the API help file for the Commands object. If you use command strings that are not documented, they may change in the next release. Autodesk will only maintain code compatibility between releases for strings that are documented.
The ability to customize the user interface for a specific class of users is another way DWF goes beyond the paper.
