If you have multiple macs on your local network (home or work), you can share printers with all of the macs. I have an iMac and two iBooks. The iMac is connected to my printers, and I have enabled printer sharing, so my iBooks can print to those printers. Here is how to do it: First, open System Preferences. Apple menu -> System Preferences Next, choose 'Print & Fax'. Click on the 'Sharing' tab. Now, add a check mark next to 'Share these printers with other computers', and then add a check mark next to any of the printers that you want to share. Now, these printers will show up in the 'Print dialog' box when you try to print on the other machines.
