I have all my plans scanned into tif files. Look around for a graphics company that produces copies of blueprints or architectual plans. I have a place close by me that will scan up to 8 plans 36" wide by 84" long for $20 plus $10 to copy to a USB drive. Then I use a wide carriage (16") dot matrix printer, I got off ebay, to print out the sections I need. This way I don't have to ever use the original plans except for reference.

Oh ya, almost forgot, if for some reason I need a new copy I can take the tif files back to the copier company and have them print out a new copy. Another cool thing is that I can use the digital files to change or modify the plans.
