Sorry if this isnt in the right place...Anyway so ive got all my old photos out to scam into my macbook pro 2011 but the scanner ive got is EPSON Perfection 3170 PHOTO, Overview - Product Information - Epson America, Inc.
The scanner is quite old so i have to use image capture with it. My question is should i buy a newer scanner for about £40 something like from here
All-in-one printers Buy online | Currys
However my current scanner is an actual photo scanner whearas the ones im looking at are all purpose printers but are nearly a decade newer, so maybe better at photos anyway. Also what resolution should i scan the photos to so if i actually put them on a cd and got them printed in a shop they would look good.
Thank you for any suggestions.
