Hey Xfactor, I did not typed it down but was thinking - adding a bulk ink feeding system should reduce the cost significantly on Epson, don't you think? I mean if person is considering a laser printer and not a large one, they don't need 100 books a day or more to print...
As far as my original reply - we get quiet a lot of "walk ins" in my printshop asking to print or copy a photographs, those that insist that we do it anyway, usually not exited with the results... The deal is #1 - You can mill the toner only by so much and molecule of ink will always be smaller than particle of toner, #2 - today's inkjet (not a $100 ones) use 6-8 colors and can reproduce photos much better than CMYK toner based machines. Yes I'd out that commercial websites offering to print photobooks using InkJet printers - Indigo is next best thing I guess.
