Start off by opening up the document you are trying to print in Word / Excel / Outlook / Acrobat Reader and either command (⌘) and “P” or by going to File > Print
Ensure your printer is selected and press the Copies and Pages drop down
In the dropdown, choose “Media and Quality”
Select the “Feed From” drop down and pick the desired tray number
Select the Presets dropdown
Save the current settings as a preset
Give the preset an easily identifiable name (e.g. Downstairs Office Tray 3)
Now, whenever you need to flick between paper trays, you can click the “Presets” drop down and select the preset you just created.
