Hello
I’m sorry, but I couldn’t find any specific information on how to specify a specific tray for printing checks using the Document Routing Agent in Dynamics 365 Finance and Operations. However, you may want to check the printer settings in the Document Routing Agent to see if there is an option to specify the tray. You can also try checking the printer settings on your computer or on the printer itself to see if there is an option to set the default tray for printing.
