Step 2: Install the model script file using HP Jetdirect Printer Installer

Make sure you have the IP address of your printer. To obtain the IP address, print a Configuration Page from the Control Panel.
  1. Log in to your root account and at the command prompt, type hppi or /opt/hpnpl/hppi to start the HP Jetdirect Printer Installer for UNIX.
  2. Type 1 for Spooler Administration.
  3. Type 4 for Install New Model Script.

    If the model script previously installed is the latest, the software will not perform any updates.
  5. Type the IP address of the printer for which you want to install the model script.
    The software will query information about the printer and install the model script if it recognizes the type of printer.
  6. If the type of printer is not recognized (if the software cannot currently communicate with the printer, for instance), do the following to install the model script:
    1. Type y (yes) to continue installing the new model script.
    2. When a list of printers displays, type the number corresponding to the printer Model in the list for which you want to install the model script.
