If the electric potential of CS1 is higher than that of CS2, the printer is ready for communication
(the host is ready to receive data). If the electric potential of CS1 is lower than that of CS2, the
printer is not ready for communication (the host is not ready to receive data).
If the electric potential of DR1 is higher than that of DR2, the printer is ready for communication
(the host is ready to receive data). If the electric potential of DR1 is lower than that of DR2, the
printer is not ready for communication (the host is not ready to receive data).
Switching between online and offline
