Hi
I found the best OCR at 600 DPI. I am using the OCR software that came
free with my HP 5000 scanner. I am currently in the middle of scanning my
textbooks for my class in the University. So, you know I have to have pretty
good OCR for that.
God bless,
Mark
God Loves you!

Hello all,
I'm going to buy a scanner. What specification should it need to OCR such as
how resolution, bit depth, dynamic range and etc?
Thanks in advance,
Nam
