Conditions for Bidirectional Communication

To support bidirectional communication, the following conditions must be met:

When connected with parallel cables

  • The computer 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.

When connected with the network

  • The Standard TCP/IP port must be used.

  • The TCP/IP protocol or the IPP protocol is used. (When using the IPP protocol, the IPP port name must include the IP address.)

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.

  • [Enable bidirectional support] must be selected, and [Enable printer pooling] must not be selected on the [Ports] tab with the printer driver.

Note

  • The PCL 6 and PostScript 3 printer drivers support bidirectional communication and automatic machine status updates.

  • To obtain machine information automatically using the bidirectional communication function of the PCL 6 or PostScript 3 printer driver, you must select the [Automatically Update Printer Information] check box on the [Accessories] tab in the printer driver's properties window.

  • The PCL 5e printer driver supports bidirectional communication. You can update the machine status manually.
