It's always better to scan from print film or slide film. You get far more contrast, and far more detail, and it's not second generation. A pixel, on the other hand, is a dot capable of the full colour range. You need lots of dots to make a specific colour and not look spotty. To render a pixel well can require scores of ink dots.
Most printers can only simulate continuous or near-continuous tone.
