Something like this: https://a.co/d/0aUeoHAb There are a variety of them on Amazon for under $100. They all use Bluetooth and an app for printing from a phone, you can plug them into your computer and they act like a USB printer. I splurged and got a more expensive one, it connects to Wi-Fi and uses AirPrint so you can print wirelessly from a Mac or iPhone, no app required. For how much I use it, it was worth it. https://a.co/d/0eCLmp6X
