Do these printers support cable connections? #49

I just wonder if it is possible to communicate via wires instead of Bluetooth? Does USB work as an interface or just for power?

Some of the printers do support serial over USB. I believe the MTP-02 supports that. You would need to test each one. The less expensive cat/rabbit ones don't appear to support serial over USB, but might have an internal serial connector that you could use if you open the case.
