jetadmin

Jetadmin is the utility with which you can administer HP Network Printers.

jet admin was buggy all it's life it is replaced not, i think with webadmin with has security considerations i think. i just use the hp add network wizard, a small unobtrusive applet downloadable for various window's os's from www.hp.com. what these tools do is discover the printer device for you when you don't have the ip address. they also allow you to configure the nic on the printer for protocol, ip address, subnet mask etc

Jet admin was a tility to manage hp jet direct print servers. it has been replaced with hp's webjetadmin which is a utility that has its own webserver that runs on your computer it runs a discovery on your network for jet direct print servers. it also will find other manufacturers webservers but will not always manage them. you need to use a web browser to run connect to the webserver and manage the printers also these utilities allowed you to update firmware.
most newer jet direct cards have a built in webserver so you dont need this utility often anymore. I did like the old jet admin utility better because it used less system overhead.

Personaly, I still user jetadmin. My current network is not that big, but I have worked in enviroments that had hundreds of printers per building in a campus of buildings. JetAdmin was perfict. You could use differend DBs on a laptop in different blds. A DB refresh would take... well a long time, but if you have the MAC of a new printer, finding it didnot require a discovery.
