    Typically, on a PC, it would be either CTS (pin5) or DSR (pin 6) on a DB-25 connector. Communicates with the host to determine if the printer is ready to receive data by sending “XON” (HEX 11H) or “XOFF” (HEX 13H) code to the TD line.

  • Page 26: Ieee1284 Parallel Interface

    IEEE1284 signals are not detected, it will operate in the slower standard Centronics mode. For this reason, an interface cable and host interface conforming to the IEEE1284 specification must be present to fully utilize the speed capabilities. This interface also operates bi-directionally and can report the status of the printer back to the host.

  • Page 27: Universal Serial Bus (Usb) Adapter

    The Universal Serial Bus (USB) interface is a Plug-In Interface Module that can be installed by the user. It requires a driver (shipped with each printer that has the interface installed) that must be loaded onto the PC and configured to support USB peripherals using Windows 2000 or above.

  • Page 115 A protocol for controlling the flow of data between computers and other devices on an asychronous serial connection. For example, a computer typically sends data to a printer faster than the printer can print. The X-ON/X-Off printer contains a buffer where data is stored until it catches up, a small microprocessor in the printer sends back an Xoff signal to stop sending data.
