I think that you should find the “Printing Preferences” dialog for your printer. This depends on Operating System. For example, in Windows 10, you can go to Search (press <Win+S>), then type “printer” and select “Printers &
scanners” from search results. Then continue navigation until you find your printer and commands like “Manage” and “Printing Preferences”. Set the options related to paper source.
Also consult the manufacturer’s manuals.
