Thanks Bill for the offer. Art Post's request is just fine. The problem with HP's specs, at times, is that the real world doesn't match the specs. That's why I asked the question the way that I did. Real costs...Real times for printing and copying CAD drawings of D size. Another help would be advantages of 240W Scanning / Editing workflow compared to HP 815MFP. Right now I'm trying to sell a 240W and an Encad T-200 to match a customer's workflow. That is, mostly B/W with very little color demand. Thanks for your help.
