Conditions for Bidirectional Communication
Bidirectional communication allows information about paper size and feed direction settings to be automatically sent to the printer. You can check machine status from your computer.
To support bidirectional communication, the following conditions must be met:
When connected with parallel cables
The computer must support bidirectional communication.
The machine must support bidirectional communication.
The interface cable must support bidirectional communication.
The machine must be connected to the computer using the standard parallel cables and parallel connectors.
Under Windows 2000, [Enable bidirectional support] must be selected, and [Enable printer pooling] must not be selected on the [Ports] tab with the printer driver.
When connected with the network
The machine must support bidirectional communication.
The standard TCP/IP must be used.
[Enable bidirectional support] must be selected, and [Enable printer pooling] must not be selected on the [Ports] tab with the printer driver.
In addition to the above, one of the following conditions must also be met:
The TCP/IP protocol must be used.
IPP port name must include the IP address when using the IPP protocol.
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 printer driver supports bidirectional communication and updates the machine status automatically.
The PCL 5e printer driver supports bidirectional communication. You can update the machine status manually.
