What does the terms (enhanced,hardware and optical) scanning resolution means?
I’ll put them in order of the best to worst types. Optical is what that actual scanner optics are reading while scanning the document. This is the “true” picture of the image. Hardware is essentially where the scanner itself has some image ‘editing’ capabilities due to a chipset installed in the scanner and takes the lesser optical scan and will change the image to make it ‘look’ like a higher resolution (more dots per inch), when it actually is just taking 4 optical dots and turning it into 8 by merging colors/edges/etc. Enhanced would be the same as Software (comparing to Hardware above). This would just be that the software running in your operating system that is doing the scanning is further refining and merging/smudging colors & edges to where the resolution looks even higher. In our example, you might have a scanner that is 1200 optical, 1600 hardware, and 2400 enhanced just because each step along the way the image is being processed more away from it’s true self into a merged
