Conditions for Bidirectional Communication
To support bidirectional communication, the following conditions must be met:
When connected with the network
The Standard TCP/IP port is used, or the TCP/IP protocol or the IPP protocol is used. (When using the IPP protocol, the IPP port name must include the IP address.)
[Enable bidirectional support] is selected, and [Enable printer pooling] is not selected on the [Ports] tab with the printer driver.
When connected with USB
The machine must be connected to the computer's USB port using the USB interface cable.
The computer must support bidirectional communication.
The PCL 6 and PostScript 3 printer driver support bidirectional communication and update the machine status automatically.
The PCL 5e printer driver supports bidirectional communication. You can update the machine status manually.
