Choosing an interface On some printers, you can attach multiple interface cables 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: a standard parallel connector, USB, or network connector. To use a port, connect a cable from the printer to the computer, then set the appropriate values. For more information, see the documentation that came with your printer. Use a 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 a USB interface when you: • Attach your printer to a personal computer, iMac, Sun Ray, or Sun Blade. • Connect the printer to a computer that does not have an available parallel port. • Attach your printer to a Lexmark external print server. Note: Attach network cables to Ethernet print servers installed in your printer.
