Many years ago I wrote about an idea for simplifying hardware devices that scan stuff producing digital images. They shouldn't require any drivers and they should work effortlessly. But the architecture they use for these devices is still rooted in the 1980s, when it should have and easily could have made the transition to HTTP.
I'm thinking about it again because I wasted a bunch of time on a Canon 700F scanner that, because of driver problems, just won't work with my Mac laptop. Now that I've got the problem I see that dozens of other users had it too (the problems didn't show up in the Amazon reviews, but do show up in various support forums).
How to use it: Lift the lid, put a document in. Close the lid. Press a button. Refresh the home page of the scanner and click the Docs link. A list of docs in reverse chronologic order appears. To view a doc, click its link. To download, right-click its name and choose Open or Save or whatever other options your browser allows.
