The printing feature is now live in the Web Crew Training Application. It allows cadets and commercial pilots to conveniently print their documents, however, only specific documents are allowed to be printed.
When you see the disabled print icon with a tooltip message stating "Document not available for printing due to licensing agreement", it's because that document is either customer documentation or CAE documentation that is not allowed to be printed.
For the documents that can be printed, you will see the print icon enabled. Once you click it, it will open a printing window where you can select pages and include comments, annotations, etc.
Note: A watermark will be applied to the document for proprietary purposes and it is advised to limit printing to one copy.
