I thought it was possible to scan by connecting to a computer but it was not. It is mandatory to put a micro SD card on it and discharge it by connecting it to the computer.
The quality of the scans is very good compared to the price of the scanner to the leaves, administrative papers or books. By cons to scan pictures, this is not ideal. The colors are faded, less strong.
I always scans on average (1500ko) or high definition (3000ko) and pdf format. There are no big differences in quality. Right scanner is not easy but once the hand that is easily taken. I put a large white sheet underneath the scanner being wider than a sheet 21x29,7 it also scans the media.
My only two complaints causing him to lose a star are without a battery (battery required) and almost impossible to scan pictures with (the photo is too degraded).
Otherwise it is really good and convenient to scan various papers or books.
I put below the product photos and a sample book scanned to report to you on the quality.
