By both Xerox's and InfoTrends' account, the answer is yes. With the release of the ColorQube 9200 line, Xerox is offering tiered pricing for prints. Normally, companies pay for printing on a per-page basis. Black and white pages are 1 cent each; any page with even a trace of color (say, a blue hyperlink or a company logo) costs 8 cents.
By contrast, Xerox says it will charge 1 cent both for black and white pages, as well as pages with minimal amounts of color. Pages with an "intermediate level" of color -- such as a chart or an image -- would cost 3 cents. Only pages containing a large quantity of color would cost 8 cents.
There are certainly other considerations when MFP shopping, including speed, print quality, and features, but given the nature of my blog, I've chosen to hone in on the environmental considerations of the ColorQube line. From that perspective, Xerox has come up with a remarkable technology, one that demonstrates how even seemingly small changes to a product component and its packaging can have significant environmental -- and economical -- benefits.
