Slowdown in selecting printers after SP2

I just updated several of my computers to SP2 and one of them glitched on me. It works great for the most part, but when you are in anything you want to print and select File-Print, it takes up to 23 seconds for the print box to show up. If you just use the print icon from the toolbar, it works great. But if you need to select a different printer, you can feel yourself growing older waiting for it. The worst part of it is this is my bosses computer. He’s been good about it so far, but any help would be great.

Thanks
