that you can edit on your computer.

during scanning:

HP Scanning (Select Document.)

The software might not recognize text that is tightly spaced. For example, if
the text that the software converts has missing or combined characters, "rn"
might appear as "m".
◦
The accuracy of the software depends on the image quality, text size, and
structure of the original and the quality of the scan itself. Make sure that your
original has good image quality.
◦
Colored backgrounds can cause images in the foreground to blend too much.

If the scanner glass is dirty, the scan file does not have optimum clarity. Make sure
the scanner glass is clean.
Issues with text recognition (OCR) (Mac)
If you scan text but cannot edit it, check the following:

200 dpi is sufficient for storing documents as images (JPEG or TIFF is the best
for most OCR applications).
