I am ordering a lot of Age of Steam maps and 18AL and 18EU printed at an online printshop, and they mailed me that they had trouble printing the 18EU map, and now I can send them your file!!!
There are substantial borders around the parts just because the map isn't of a size that fits onto a4 easily, so you'll have some trimming. As per my experience (shown below), this isn't that much of a problem.
