[sane-devel] Webcam-like book scanners

[David Legg]

Just to add to what Torfinn mentioned elsewhere in this thread: -

I use a CZUR ET16 Plus to scan things like pamphlets and Xmas cards 
etc.  I have to use it on a Windows machine because there are no Linux 
drivers for it.  Don't think of them as simply web cams.  As Torfinn 
hinted at, the real advantage of the proprietary software is that it can 
automatically crop and rotate the image and even scan two facing pages 
at once to produce both pages as separate images.  The CZUR scanner even 
fires off a laser just before scanning so it can estimate the curvature 
of the paper.  Then there is also the addition of a foot switch to begin 
scanning if you have both hands full.

With scanners I have learned that one type doesn't suit all scanning 
jobs.  I also use a brother ADS-4700W sheet feeding scanner which can 
automatically scan both sides of a sheaf of sheets and send the PDF to a 
waiting server with the push of a button!

It's all a far cry from when I worked for Crosfield Electronics 40 years 
ago.  Those drum scanners were used in the printing industry and filled 
a room!
