As this is designed for ENTERPRISE, printing from the within the APPS will make PowerApps superior to Excel and even ERP / SAP system. If ONENOTE can be accomplished (for printing) after our request, why not PowerApps.
Thanks everyone - to expand on Emma's reply below on the various types of "printing" that were identified in our recent survey, and the report capabilities already available in CDS, we are beginning engineering work for Canvas App export to PDF and are planning to release this functionality in February 2021. We understand this feature is hotly anticipated and are excited to get this underway. As soon as we can make early preview or experimental features available we will and will continue to provide updates on this idea, and on our blog.
Thank you to all the members of our community that have voted, provided feedback and been patient as we work to get this work underway.
