perhaps you could scan it in chunks, put it back together and project it onto some lining paper.
or divide the whole thing into a4 grids and print on a3 paper on a normal photocopier that has an enlarge % setting. glue back together.
the plan printer option may not be too expensive if you do it in 2 a1 halves and get them blown up by a %. It's years since my engineering days though so I've not kept up with plan printing prices.
