Scanning for photo processing

[Howard MacGregor]

Can anyone tell me what is the best resolution to use when scanning photos
(b&w and color) that will be subsequently sent to a commercial processor
for paper prints,
If it makes any difference, am using Microtek E6 and working with Photoshop 4.
Also: What is the best resolution to use (again b&w and color) when
printing to an HP Deskwriter 660C. (Search-engined all over for this but
canšt unearth the answer I need.)

My ISP is wonky on serving up news lately (nothing at all today and donšt
know if this is even going to be posted) so an e-mail reply would be
appreciated.

Thanks.
