Pat,
RET is HP's "Resolution Enhancement Technique" (other manufacturers
have about the same thing but have to call it another name to distinguish
from the competition's) which basically means that you throw a 300x300dpi
graphics file at the printer and it will "interpolate" (kind of guess
where an additional in-between-dot should have been if the graphic was
300x600dpi). The DJ520 and DJ560C can do this (in B&W only) which means
that diagonal lines will look a bit "linier" and curves "curvier" than in
300x300dpi without RET. I believe characters are also printed in enhanced
resolution as standard.
BTW, scanners usually do the same thing the other way round: the scan
at, say, 600x600dpi and interpolate in-between-pixels to give a graphics
file of 1200x1200dpi enhanced resolution.

Ah, I see! So, when I'm printing at my driver's 300 x 300 dpi, this RET is
in there, making my print look better automatically! This I can live with!
Thanks again. *B^) Pat L.
