Does it have a USB port for a cable to a computer?
Not a slot for a USB stick or an SD card: those only load files. We're looking for a port a computer can print through.
How to tell
- A USB-B port (the square kind on older office printers), mini-USB, micro-USB or USB-C, usually on the side next to the SD card slot, or at the back.
- Most printers with a small screen and a turning knob have one, like the Creality Ender-3 and Ender-5, the Prusa i3 MK3 and the Anycubic i3 Mega.

Through that port, another device can feed the printer the print a few commands at a time, which is called serial printing. Printers like these usually run Marlin firmware, and most were made before 2023.
To check, plug it into a computer with the printer on. On Windows it shows up in Device Manager, under Ports (COM & LPT). On a Mac, open System Information and look under USB. On Linux, run lsusb.
A printer with this port connects through OctoPrint on a Raspberry Pi: the Pi plugs into the port and connects the printer to SimplyPrint.
