Q: Paper size default in Print Preview

I do not have the option to "Save current settings" on my print window. My son-in-law was over and fixed it in one minute. Went to system preferences; then to Printers & Scanners; then changed the default paper size to US Letter.

Thanks for trying to help! I sent this in a reply (I do not have the option to "Save current settings" on my print window. My son-in-law was over and fixed it in one minute.
