Counterintuitive C309a scanning resolution result

[amylarson]

I'm working on a photo archival project and was testing scanning at various levels of resolution.  With my Photosmart C309a I scanned the same photo @ 200, 300, 600, & 1200 dpi.  The resulting file sizes grew as expected.  However, the resulting prints (from the C309a) appeared to less crisp and "more interpolated" the higher the resolution.

I haven't been able to figure out the print resolution of the C309a . . . perhaps the printer is the problem?

I started w/ a 4x5 film-based photo, printed 8x10 photos, running Leopard on a MacBook Pro.

Thanks.

I was doing the same thing on my  c309g.  Scanning at different dpi and checking quality.   Can you tell me how long it takes you to scan at each dpi?  300.. 600 and 1200     Mine is a few mins at 300 but 10 mins for 1200.   I seem to be wasting my life away waiting for the scanner to do its thing.

Thank you for any info you can provide

That sounds about right to me.  I did the scanning over a wireless network and wasn't super attentive to the elapsed times, though.  Next time I dig in, I'll time it and let you know the results.
