HP 5m C3917A, C2021A, 5n C3952A Printer I/O Configuration, Parallel Menu, Serial Configuration

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 bi-directional communications between the printer and the host. The default setting is ON. This default setting (ON) must be active in order to use 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 from the computer. If you need to locate the printer between 51 and 2000 feet from the computer, use an RS-422A serial configuration (not available on the LaserJet 4 Plus or 5).

Since the default-printer I/O setting on the printer is parallel, remember to change the settings on the printer control panel for serial printing.

Serial Protocol

When printing with a serial configuration, the same protocol must be set on both the printer and the computer. Protocol on the printer is set by changing the control panel. Protocol on the computer is set by using DOS commands. The default protocol settings are described below.

BAUD Rate

The BAUD-rate setting tells the printer how fast information is transferred to and from the computer. The default BAUD rate setting is:

BAUD RATE=9600*.

Configuration 3-33
