Printer I/O Configuration Parallel Menu The default setting for the HIGH SPEED PARALLEL I/O is YES. If it is set to NO, the interface runs at a slower speed that is compatible with older computers. When the default is set to YES, the parallel interface runs at a higher rate supported by newer computers. Advanced Functions The ADVANCED FUNCTIONS feature of the printer enables bidirectional communications between the printer and the host. The default setting is ON. This default setting (ON) must be active in order to use HP LaserJet Explorer, the Windows® Printing System, and other software applications and drivers. Serial Configuration Use RS-232C serial configuration when the printer is located 11 to 50 feet (3.35 to 15.24 meters) from the computer. If you need to locate the printer between 51 and 2000 feet (15.54 and 610 meters) from the computer, use an RS-422A serial configuration. Serial I/O settings must be configured correctly for proper serial communication.

Protocol on the computer is set by using DOS commands. The default protocol settings are described below.
