28 Chapter 2 Getting to Know Your PowerBook
Keeping Your Software Up to Date
You can connect to the Internet and automatically download and install the latest free
software versions, drivers, and other enhancements from Apple.
When you are connected to the Internet, Software Update checks Apple’s Internet
servers to see if any updates are available for your computer. You can set your Mac to
check the Apple server periodically and download and install updated software.
To check for updated software:
1 Open System Preferences.
2 Click the Software Update icon and follow the directions on the screen.
 For more information, search for “Software Update” in Mac Help.
 For the latest information about Mac OS X, go to the Mac OS X website at
www.apple.com/macosx.
Connecting to a Printer
Follow the instructions that came with your printer to install the required software and
connect the printer. The drivers for most printers are built in to Mac OS X.
You can connect many printers with a USB cable; others require a network connection,
such as Ethernet. If you have an AirPort Express or AirPort Extreme Base Station, you
can connect a USB printer to the base station (instead of connecting it to your
computer) and print wirelessly. For more information about your USB ports, see “Using
Universal Serial Bus (USB) Devices” on page 34. For more information about a wireless
or network connection, see “Understanding AirPort Extreme Wireless Networking” on
page 39 and “Connecting With Ethernet (10/100/1000Base-T)” on page 43.
