As the above say, it's easier just to stay away from the dock option. It's only for that specific camera, and even though it's perhaps easier to use, if you ever want to be able to load the pictures up on your computer and play about with them (improve them, etc.) then you'd be much better off getting a decent proper printer as wideboy suggests. And that's half the fun of digital! Or just do as ronaldo suggests. The cameras come with little cards that store the pictures on them (you'd be well advised to get a larger capacity one at the same time as buying the camera; they ones they come with don't store much). you just hand the card to the guy in your supermarket or boots etc., and they'll print the things for you.
Take a look at the Casio S500. For general use, it's a brilliant camera. If you like something with more manual controls, then the Z750 is a great option (or its successor the Z850).
