I had a difference of opinion with a co-worker regarding printing screenshots. My position is to Never re-sample them. If it ends up being 72 dpi, or 120, or 300 etc. at final size, I say just scale to final print size, convert it to CMYK, but don't resample it. The co-worker says she doubles the size (doubling the pixels), sharpens it, then sizes to fnal size while resampling to 300 dpi. My opinion is that you will only reduced quality by resampling. Especially since screenshots have so many 1 pixel lines, text etc.

What are your thoughts?
