As I mentioned to Bigiron in another thread, I found an inexpensive source for copies of plans:

UPS Stores, I guess mostly in large cities, or places where there's a lot of construction work going on, have large 100% copiers. The paper is not eternal archive quality, but quite good.

The copies I got at my nearest UPS Store were the most accurate first-pull copies I've seen in years. On a light table or against a plate glass window/door, the lines superimpose - dependably.

For how much? Around here, $2 plus sales tax per. (Pretty much single width, length irrelevant!)

Might be interesting to see how widespread these UPS Stores are around the country...

WB,

Not sure. Width is about 42". Paper is on roll: -  the length isn't likely to be relevant.

Local store machine has been adequate for everything I've needed so far.
