What you can do with it
- Cheaper office printing
- Force grayscale before sending to a mono printer queue.
- Uniform archival look
- Normalize mixed color/scan packets to gray.

Grayscale vs scan cleanup
Grayscale keeps soft gray levels. Scan cleanup forces pure black and white with a threshold — better for muddy phone scans, harsher on photos.
Raster output
Pages become JPEG images. That is fine for printing and sharing; keep a vector original if you still need selectable text.
