You upgraded to Leopard, now when you print, the Printer queue opens in the Dock. Great. But what happens when you're done printing? It's still there. The print queue is like a guest who won't leave. You can fix this and it's easy.

You just need to do the following:

1. Open System Preferences and select Print & Fax:

2. Open a print queue by clicking Open Print Queue... button. Now you'll see a printer in your Dock.
3. Once your print queue is in the Dock, you can Control-Click the printer icon (or right-click icon) and then select Auto-Quit. That's it!

Now your print queues will appear during printing and 'go home' after their done.

Thanks...
