It would be conveniant to be able to print an attachment without the need to open or save the attachment first.
This could be a print option in the menu that opens when you right-click an attachment or an option in the preview pane when you hover over the attachment.
Try this. Create a shortcut to your printer on the desktop, and then drag and drop the file attachment onto the shortcut. See if that works.
Ps I don’t have a printer to test that but in theory that should work.
I only have a network printer and the suggested workaround doesn’t work, I can’t drop a document on the shortcut.
Also, the suggested workaround doen’t work on mobile devices. A print option in the menu after right-click or long press world be great.
