Do I need an all-in-one with scan, copy, and fax?

If you ever need to digitize receipts, sign-and-return PDFs, or copy IDs, an MFP (multifunction printer) is worth the extra $50-$100 over a print-only model. Fax is increasingly optional, most ‘fdw' models include it but you can skip to a ‘dw' MFP if you don't need analog fax.
