If you often print with different paper sizes on a Mac, you can get frustrated if the system is stuck on the wrong paper size that you don’t want to use. Fortunately, it’s easy to set the default paper size for all printers on your Mac. Here’s how.
First, click on the Apple icon in the top left corner of the screen and select “System Preferences.”
When System Preferences appears, click “Printers & Scanners”.
Look in the Printers & Scanners preferences at the bottom of the window. Find the option labeled “Standard Paper Size” and click the drop-down menu next to it.
From the Default Paper Size menu, select the paper size you want to use as the default. This setting applies to all printers installed on your Mac.
After that, close System Preferences and you’re good to go. Have fun printing!
