Local printing module for multiple images

Hey all, not sure if this is the right forum to ask this, but here goes..

Does anyone have/is working on a module that allows you to print your shopping cart contents to a local printer?
I'm working on a coupon site for a client, and one of the features we talked about would be the ability for you to print said coupons out on a local printer, by selecting which ones you want printed then clicking Check Out.

If anyone would be interested in writing something quick and dirty to do this, I would be eternally grateful.
