Image quality:
As Andrey indicated, on typical color lasers and inkjets, you need 300 dots
per final printed inch (~120 pixels/cm) for maximum quality . A small 4"x3"
illustration would need to be 1200x900 pixels ("ray 1200,900"). Full page
11"x8.5" (ray "3300,2550").
Since rendering those images takes forever and the files get really huge, I
tend to trade quality for time and space, and stick with 150-200 pixels per
inch (~60-75 pixels/cm) for draft/in-house printouts.
Cheers,
Warren
