Sean,

Kinko's is your friend. Just take the plans in to them and tell them you want a 50% (or whatever size you want) copy. They will take the full size and make your sized copy for you. If you want to pay extra they will scan the plan in and give you a digital copy so you can take it home and print out any size Tiger you want using a program such as Bipe's excellent Tileprint.

Hope this helps,
