Try switching it on electrically. Much less parts.

Nah, it'll be the same, because of MOSFET you'd likely use. And, if you use relay, without a module, it will be even twice as parts

Why using a MOSFET? Just short the power button wires in the GPIO pins.

That's REALLY bad idea. The printer may work in 3.3V and you give it 5V - printer dead. The printer may work in like 9V - boom, your GPIO pin/arduino is dead

Why guessing? Open it check.... implement.

I'm saying about the no-MOSFET idea. Yeah, sure, it may work but it will be really bad imho

Wonder if it has wake on lan settings.

prolly should have checked that first 🤦🏻‍♂️ oh well, ya live, ya learn. it had eco power enabled.

What type of arduino is it amazing work.

thanks! Nano RP2040 Connect with built-in wifi

nice i plan to make it compatible with my app so that anyone building a smartlock no mather which microcontroler can use the app currently in the works of that.

do you have any questions or challenges at this point?

The printer is just like me and really good at taking naps. I built this little device to turn on the printer from a web click. The Arduino connects through my Wi-Fi and checks a file on a remote server every second. I use a simple website to toggle the servo from anywhere. Next up, better form factor :)
