Hello Benjamin Bell2
In "printer preferences" you may look for an option that allows you to specify the paper source or tray for envelopes. This option may be labeled as "Paper Source" or "Tray Selection". The exact options may vary depending on the specific printer model and printer driver.
Check if there are separate settings for trays and paper size. This allows you to configure the printer driver to automatically select the correct tray and paper size based on the print job. If you only see one set of options, you may need to manually press the button on the printer. As some printer drivers don’t have separate settings for different paper sizes and types.
You could also consult the printer manufacturer's support for assistance specific to your printer model.
Best regards,
