3. From the hard drive, click Applications, then click Utilities and select the Printer Setup utility.
4. Click Add.
5. If your printer shows up in the printer list, select Printer. If the printer does not show up in the list, choose either Bonjour or Rendezvous as the connection type and then select the printer from the list.
6. Under the Print Using list, select HP.
7. In the list of available drivers, select the HP Photosmart P1000 – Gimp-Print driver.
8. Click Add.
NOTE: Using the Gimp-print driver might provide basic print-only functionality. This driver is a built-in driver in the Macintosh Operating System and will not provide all of the features that are provided using a direct USB connection.
