If your friend wants full control over the result, and minimum hassle with file sizes, transfer etc, the way to go is PDF. He sets up the correct page size, "prints to file" using the PDF format.
He can use the free PDF creators (Amyuni delivered with Archicad on the PC or the system's built-in in MacOSX) or, to get more control, buy Adobe Acrobat Standard (probably enough) or Professional.
He sends it to you and you print it using Adobe Reader (free, download from adobe.com). Remember to set page scaling to none.
Note that if you have any version of Photoshop, and upgrade to Adobe's latest Creative Suite, Acrobat is included in the package.
