Of course the plans are now in supersized image scan tiles, which can be downloaded and re-assembled in to massive jpeg images and then printed off using a drawing print service for about £7 a drawing with no minimum order.
But trust me it takes about two weeks per scan to re-assemble the tiles as there about 2500 tiles per image scan.
Oh if you want to do it use Firefox and a plugin called Pick & Save Images, open a plan zoom right in then use the app, it will then grab all the tiles visible for that area of the plan, it's then a matter of manually re-assembling the tiles in Photoshop.
