I have been using http://www.afullcup.com/forums/index.php?referrerid=84695 there is no fee, they have a huge database to printable and other coupons, plus there are forums for every store with real woman who post the deals they find all day long, this site has saved me huge amounts of money.
As far as printables each store has their own policy, some stores require they are printed in color other stores only require that the coupon can be scanned, you can ask your store their policy and also look under the forums on A full cup most have the store policy listed but it also varies from state to state.
Joining coupon trains is a great way to get rid of coupons you wont use and trade them for ones you will use, I send and get back an envelope every week, I LOVE IT! My coupon stash grew by 5x's the amount i had before joining this site.
