Enforce Classification on Print/QuickPrint
Enforce Classification of document before print or quick print. i.e. a user opens an unclassified document to print. The system should force the user to classify; otherwise, the document will not be printed.
This will help enforcing a classification even if document is printed as PDF file.
Regarding the previous comment, the current behavior in Office is actually that if the user doesn't have the EXPORT right (which officially controls whether a user can save the file in unprotected format) the file can't be saved in PDF format. So while inheriting the protection on export in PDF format would be a desirable feature, the current behavior in Office doesn't create holes that could cause data leakage.
It is only if you have the PDF plugin from Adobe installed that the plugin overwrites this functionality with one that allows you to save the file in unprotected format with only Save rights. As such, I suggest filing a bug with Adobe, not with Microsoft.

Microsoft print to PDF should inherit the classification of the source document. Should this be submitted as a bug? Creating unclassified files from classified files is a huge opportunity for sensitive data loss!
Protection should be invoked/applied when a user sends the print command on any document as opposed to current behavior where it comes into action only when the document is saved or email is sent.
Agreed. Opening and printing a new document should require Classification before being printed.
Currently the Marking is only applied on document save and email sent.
