2. Enter the printer's IP address in the Address text box. Don't know what the address is? Not to worry. Print out a Configuration Page. For my 4000N, I used the Menu and Item buttons on the printer to get Print Configuration to appear in the LCD screen; then I hit Select. On the resulting printout, I located the line that said IP ADDRESS.

If things go well, shortly after entering the IP address, the Print Using line at the bottom of the window will list the name of your printer (as seen on the right). If so, click the Add button and you are done. Your printer should be ready to work with Snow Leopard.

If you have another brand of printer, you'll likely need to choose Internet Printing Protocol - IPP instead of HP Jetdirect. And there will be a different means to determine the IP address. But the basic procedure remains the same.

One bit of good news: You shouldn't have to install any new printer driver software. The latest versions are already installed via the Snow Leopard upgrade.
