how do i add a printer

Apple menu -> System Preferences -> Print & Fax or Scan depending on the version of Mac OS X.

Apple menu -> Chooser in the older version of Mac OS known as 9 and earlier.

That works assuming the driver has already been installed on your Mac.

You posted in the forum of Apple's old Microsoft Office competitor called AppleWorks which predates iWork's release of 2005. Go to Apple menu -> About This Mac to tell us your Mac OS or Mac OS X version, and what printer you are trying to connect. You may find some resources on my FAQ*:

If not, once you know your operating system, post to the correct forum the results:

And say you've looked at my FAQ.
