While the inkjet vs. laser battle is hot in the home market, it's gearing up in the professional print shop market as well, according to this article over at AustralianIT.
Between the tremendously expensive offset presses, which operate by transferring an inked imaged from a plate onto paper, and the newer, cheaper Xerox laser printers, there hasn't been much room in the high volume market for inkjets, but that's soon to be changing as Kodak, HP and other printing manufacturers get ready to enter the field. The new inkjet presses displayed at the Drupa trade show this month will be somewhere in the midst of the field as far as initial cost goes, but at a cost per page of around a quarter of the Xerox laser printers, there's a lot of potential for the new inkjets to make a big impact in professional printing.
