Can I set up quick books to print from a certain tray on my printer

I appreciate you for taking the time to post here in the Community, @tanastor-gruccio.

QuickBooks Online cannot currently print from a specific tray in a printer. However, you can provide your feedback directly to our Product Developers, who are keen to receive your input and encourage you to share your suggestions through the feedback feature.

To send your input, here's how:
