Question : Problem: HP JetAdmin Utility does not list printer.

I have a Laserjet 5si which was configured for another network.  I did a cold reset.  I now have a new IP address and the printer is configured.  I can ping both the IP and host name.  This printer has a jetdirect card, but when I go to the Jetdirect Admin Utility on the server it does not list this printer.  What do I need to do to see this printer?

Answer : Problem: HP JetAdmin Utility does not list printer.

If you are using Windows Xp or Windows 2000 you could try the following procedure:
Select:
Start -> Printers -> Add a new printer -> Local printer -> Skip autodetection -> Hp LaserJet 5si -> Add port -> Standard Tcp/ip port

and insert here the ip address assigned to your printer.

Not all JetDirect card are compatible with Standard Tcp/ip port monitor, sometimes you need to use Hp Network Install Printer Wizard (Hp JetAdmin utility has been discontinued) to install Hp Tcp/ip port monitor, available here:

Remember to turn off firewall (installed by default with Windows Xp sp2) before using printer discovery feature, it could block network scan performed by the Hp utility.
