Many people use the tools in Adobe Acrobat and related software (such as PDF exporting from MS Word) to add basic security features to their files. One such facility frequently required is protection against printing – essentially this disables the print menu and toolbar icon in Adobe reader and other Adobe products that display PDFs.
However, for some time now Adobe have recognized that this feature is not secure, because it is not part of PDF standards and other PDF reader providers do not implement this Adobe-specific feature. Indeed, Adobe Acrobat now displays a warning message to this effect (as shown below). For example, an Adobe print-protected PDF can be opened in Javelin for Windows and printed, with no problem at all! However, using the Print protection in our Drumlin PDF publishing software does provide such facilities, as the secured file is only readable using Javelin PDF readers (after authorization). Drumlin protects against printing of PDFs when you want to fully protect your PDF in this way, but also allows you to enable printing but restrict such printing to physical devices and specified numbers of pages.
