.. warning:: You should **never** directly connect an printer with RS232-interface
|
|
(serial port) directly to a Raspberry PI or similar interface
|
|
(e.g. those simple USB-sticks without encasing).
|
|
Those interfaces are based on 5V- or 3,3V-logic
|
|
(the latter in the case of Raspberry PI).
|
|
Classical RS232 uses 12V-logic and would **thus destroy your interface**.
|
|
Connect both systems with an appropriate *level shifter*.
