Something I picked up along the way purporting to deal with the relationship between DPI and LPI on different devices, most people scan at too high a resolution for their output device and end up wasting space and getting less than perfect results due to software interpolation.

so, try these settings next time, see if they’re better.

What DPI to use:

Output to: Scan at:

laser printer (300) 120dpi

laser printer (600) 150dpi
ink-jet (300) 110dpi
