Shel, I haven't read any other responses yet, but I am getting very good
quality prints by resizing the image to 15cm x 10cm, at 720 dpi in
Photoshop. I calculate this will give me a 30x20 at 360 dpi if I need
it.The prints are then made either at home or by the lab and, at home, I set
the printer to it's best photo-quality on Premium photo paper: I have
produced A4 size prints with this method of very high quality - check with
Ryan Lee!
I also made three CD's of family snaps recently, using the same methods, and
all were printed without problems by the local 1-hour shop, admittedly only
to 15x10, but were very satisfactory.
I think it's worth remembering that the ppi factor is the printer
resolution, and has little to do with the image resolution - dpi. Whatever
the dpi, the printer will normally use 200-300 dpi for good to high quality
prints.

Subject: PPI for Printing
Whenever I have prints made on the Lightjet or the Frontier, I use 300ppi
to 330ppi or so for the resolution (is that the term?) which gives me a
nice, big, richly detailed print from scanned negatives. Using the same
resolution with the DS results in a much smaller print size, on the order
of 6x9. The lab people around here recommend the greater ppi for quality
work.
I've also heard that 240ppi is acceptable, although that it's used more
for
inkjet prints.
So, what ppi do you use for what size/type prints? If all I can get are
small prints using the recommended ppi from the digi, well, that's an
unhappy circumstance. But it seems that many of you are getting larger
than 6x9 prints from the DSLR.
