• Mac OS X 10.5: Included printer drivers 
• Mac OS X 10.4.4: Included printer drivers and PostScript PPD files for Intel-based Macs
  

TIP: When you get a new printer, don't install any drivers. Attach the printer and see if OS X recognizes the printer first.
To do this:

1. For USB printers, attach the USB cable to the computer then turn it on.
   
2. • See if OS X recognizes it:
   • • For Leopard (X.5), go to Apple menu>System Preferences>Print & Fax.
       
     • For Tiger (X.4) or earlier, go to Applications>Utilities>Printer Setup Utility.
     • Your printer should automatically appear in the printer list.
   • If it does not, try rebooting the Mac and checking your Print & Fax System Preferences one more time.
   • If it doesn't show after this, then install the drivers. Rarely do you ever use the included CD/DVD. Its often best to download them from the manufacturer's website.
3. For network printers, you'll need the IP address first. Then go to Apple's website for more details.
   
4. • X.5 =  Setting up Network printers.
