I've actually rescaled and printed drawing from MS Paint. When you print from Paint it automatically tiles the image onto multiple pages - I can't even get Paint Shop Pro to do that!
The other option is to output the rescaled drawing to a PDF. The free reader doesn't do it, but there are other PDF readers that will tile large drawings onto multiple sheets.
If it really comes down to it - for the cost of shipping, I'll print it on my plotter for you.
