Computer Connections
The parallel or Ethernet interfaces are the primary methods of sending data
from the host computer to the printer.
Note: Interface options vary based on printer model.
The RS-232 Serial Port is a secondary method of sending data to the printer.
Data transmission via the serial port is much slower and not recommended.
An Ethernet connection provides a high-speed, bi-directional connection to
the printer in networked environments.
Centronics Parallel Port
1 Using the parallel cable supplied with the printer, connect the larger
connector to the parallel port on the printer.
Note: Only the supplied parallel or high-speed IEEE-1284 parallel cable
should be used to ensure reliable performance. This cable should be
stamped with an “IEEE-1284” marking to indicate that it is a high-speed
parallel cable.
2 Lock the two metal rings on the parallel port into the connector to secure
it to the printer.
3 Connect the opposite end of the parallel cable to the host computer. Be
sure to note which port (LPT1, LPT2, etc.) you have connected the
printer to as this will later be needed for driver or software setup.
Note: The maximum recommended parallel cable length is 10 feet (3 m).
