if the original poster is talking about scanning a PRINT, then any

little but how well the printer will print ( whatever you scanned )
if it's a print - it's a "junk in , junk out" type of thing ( the
scanned print being "junk." ) For a PRINT the resolution ( for
justifying a higher ppi ) just ...isn't....there. Now if he was
scanning a NEGATIVE, then that's a different story - use 1200 or 2700
dpi and you will see the benifits.

My experience tells me scanning small prints at 600ppi is useful when making corrections or adjustments: it increases the number of pixels available for high-zoom work, spreads marks over a narrower range; and, it's essentially free. Just easier to work with, for me.

Scanning some prints made from those old negatives can yiels strining results just not available at lower ppi:

These original prints, less than three inches in the smallest dimension, really do show amazing tones and details. On my 19-inch CRT monitor set at 1024x768, the original is represented at about 10% larger than life size. And just look at this thing. Amazing.

That much resolution is overkill; consumer-grade inkjet printers
typically have a pixel resolution of between 240 and 280 pixels
per inch, and even commercial offset printing rarely needs
anything above 400 pixels per inch.

In the quoted part above, the original poster said " My scanner

printing." Which means he is indeed printing at 1:1.

No it doesn't!

IF he sets the -=scan=- for 600 and then sets the print size, the end

could have a different dpi. One of HP's and some other scanners
'helpful' over-rides.

Some of the better inkjunk and many lasers -=do=- have better
resolution than 280 ppi.
