8-6 Interfaces Deciding Which Interface to Use On some printers, you can attach multiple interface cables to the printer at the same time. The printer automatically switches to the interface receiving a job. Then it prints the job and begins searching the interfaces for the next job. One or more of the following is built into your printer: standard parallel connector, USB connector, or network connector. To use a port, connect a cable from the printer to the computer, then set the appropriate values from the printer operator panel or through MarkVision Professional. Refer to your printer user documentation for more information. Use the parallel interface when you: • Attach your printer to a personal computer. • Attach your printer to a host system with a Centronics-compatible parallel port. • Attach your printer to a Lexmark external print server. Use the USB interface when you: • Attach your printer to a personal computer or iMac. • Need to connect the printer to a computer that does not have an available parallel port. Use the serial interface when you: • Require an interface cable more than 10 feet in length. Note: Lexmark also offers a 20-ft parallel interface cable (part number 1427498). • Share the printer using a printer-sharing device. • Need to connect the printer to a computer that does not have an available parallel port. • Want to set up a receive-only fax port. Attach network cables to the Token-Ring, Ethernet, or LocalTalk print servers installed in your printer. Refer to the MarkNet™ Quick Start book or your user documentation for additional setup information.
