150 is minimal for quality print, 200 is very good *, 300 is more than
necessary and it is almost high quality poligraphy AFAIR, more than 300 is
waste of you disk space unless you want to do some digital corrections,
downsample to normal dpi and print it. This is IMHO, based on discussions
with designers.

* - I have heard that for everyday inkjets, for example, 1200dpi does not
mean 1200 dots of _any_ color on the paper, it means 1200 dots of one out
of 4 (6) colors. Each point of real color on paper is combination of 4 dots
of basic colors (CMYK) very close to each other. If it is true (and it
actually sounds quite logical), then 1200x1200 dpi printer is actually
300x300 dpi printer in the best case, and there's no reason to print an
image with higher dpi. I've tried it on my Epson 740 (720x1440dpi) and it
seems to be working: 200dpi and 400dpi prints were equal on photopaper.
P.S. If I'm mistaken - sorry! That's what I know :)
