@VanKalkerFarms - Thanks for helping out this this question. I couldn't agree more with your recommendation. The Square Contactless and Chip Card Reader is my favorite reader too! ⬜️ 👌🏻

We do not have the option of having the customer sign on the ipad.  How do I enable this?  We would prefer this over paper signatures.

settings -> signature and receipt -> Sign on device.

I read this before - there’s no “settings” option when I touch the 3 lines. It’s not on the list. What am I doing wrong?

what app are you using?  the Settings menu have been in Square POS from the beginning.  if you can't get to setting there isn't a way to setup printers or card readers etc, and you are prinitng to a printer so you had to set it up by creating print stations.
