I use a Raspberry Pi Zero 2 W as a cupsd print server. It is powered by usb from the Wi-Fi router and connected directly to an old USB laser printer nearby. Works great to print wirelessly.

I also have a Raspberry Pi 4 (8gb) with an Argon One M.2 case and a Kingston SSD. I use it mainly for coding/tinkering in C, Pharo, Racket etc. Not logged into any social media or mail in the web browser, just using it to read docs etc. Fast enough to be usable but no speed demon for sure. Overclocked to around 2GHz/64-bit OS.
