Serial (9-pin) Port (C)
The printer supports a 9-pin RS-232C serial interface. Serial interfaces
provide increased flexibility in locating the printer, but are generally slower
than paralel interfaces.
Use a serial interface when you:
•• Have a computer that does not have an available parallel interface.
•• Have a printer that is positioned more than 10 feet (3 m) from your
computer. (The RS-232C serial interface can support printers located up to
50 feet away.)
•• Are using a serial printer-sharing device.
IrDA Serial Infrared Port (B)
The printer supports an 8-pin “wireless” infrared serial interface. An
optional HP IR Adapter must be purchased separately. (See Chapter 1
of the User’s Manual for ordering information.)
Use an Infrared interface when:
•• Your portable equipment (like a laptop or notebook computer) is
equipped with an infrared transmitter.
See Chapter 4 of the User’s Manual for further information on the
optional HP infrared adapter.
MIO Slot (D)
The printer comes with an MIO slot designed to support optional HP
JetDirect cards or compatible MIO cards from other companies. (See
Chapter 1 of the User’s Manual for ordering information.)
Use a JetDirect card when:
•• The printer is used as a network printer.
•• Multiple network operating systems and/or protocols are using the
printer at the same time.
