We print engineering prints daily. While we don't print enough to justify a dedicated Oce unit, it's a great source of revenue and one we would like to continue growing.
Currently we use a Canon iPF825 MFP M40. This machine also does all our wide-format work (minus fine art and outdoor) and gives us oversize scanning. Cost per color CAD print is approximately $0.12 / sqft. (not including overhead and machine costs).
The bulk of our line drawings is B&W which we print on 20# bond, and the color renderings on 27# coated paper.
Any questions, fire away....
