I like to use a local "Reprographics / blue print" shop... they are familiar with working with large scale construction documents... they know how to print to scale.. know how to properly bind drawings... they'll even look at the cover sheet / sheet index and figure out how to assemble the drawings in the correct order... Signature Reprographics here in Sacrament are TERRIFIC....
But occasionally we run over to FedEx for small orders, as they are close / convenient...
you need to be sure that they print the file correctly... as I said above, a common mistake made by print shops is to use the print setting FIT TO PAGE... this will result in the drawing being out of scale, so really bad...
if using FedEx or similar type print service, be sure to mention to them to use PRINT TO SCALE... NOT FIT TO PAGE
also note, that if you do a lot of printing, your local "reprographics / blue print" shop may set up an account for you with greatly discounted prices... something you likely won't get from FedEx or similar service...
