usb c adapter hooked up but printer won't work.

Hi Erin C,

Thanks for coming to Apple Support Communities for help today. As we understand, you aren't able to print with a USB-C adapter.

We can isolate the issue to either your computer or the adapter by testing inside a new user account. Here's how to make one: Set up users, guests, and groups on Mac. If the printer still isn't working inside the new user, then there may be an issue with the adapter or it's compatibility wit your printer.

Have a fantastic day!
