try cups and ghostscript if using 10.2, if using 10.3, then I
believe ghostscript is built-in. Just before you click on add
printer in print center hold the option key then click "add". Or if
you prefer you can go to the web interface at <http://
127.0.0.1:631> This method seems more confusing to me but ymmv.
You can just set it up and pick a driver from the "ESP" set under
10.3. With 10.2 you need to option-add.
