Get the LaserJet 4 family DOS utility for changing printer default settings.
Download and install the LaserJet 4 family DOS utility to change the settings of your LaserJet 4 family printer, including the printer's paper size, the default typeface, or the EconoMode setting. This minimizes the time needed for changing your printer's settings, because you don't have to start the Hewlett-Packard remote control panel or walk to your printer to do so.
