[O] [OT] Scanning for archiving

[Marcelo de Moraes Serpa]

Hi list,

I just bought a scanner and started to scan important documents as a backup, and archiving them with meaningful metadata in orgmode files. Then a question came to mind - what dpi to use? I'm not really savvy when it comes to scanning or printing, and I want like a dpi that allows me to reprint the document at an acceptable quality later if necessary, but that also doesn't take that much space (600dpi pdfs take around 5MB).

Any insights welcome,

Thanks,

Marcelo.
