Oh, one more thing...if you have Adobe Acrobat (I don't think this works in the Reader-version), do the crop thing to split and save the file by re-naming into two new overlapping half files. This is to create two long and narrower prints for your copy company. Of course, their ability to work with your work is only as good as the operator.
My local Office Depot charged $10 per sheet, but could never guarantee their work. I told them they could try on their dime, and make money on my job if it worked out ok. I always carried in one full size part printed at home for proofing. They ate quite a few jobs under that agreement. Their big advantage was they don't know how to read plans...not.even for copyright info.
Conversely, the local professional copy center charged $20 to scan and email a large plan, and proofed the plan by printing only a rib full size from their digital copy and placing it on my original...one large scan, one small proof and they earned my money and respect. However we, they know how to read all sorts of plans and CAn recognize copyright info...and they were sticklers about it. No way would/could the Office Depot clerk pull-off "once and done, proofed" let alone a copyright check.
