In my experience, in larger companies, the printer, the scanner, and the photocopier are a single unit.

I think that, nowadays, you only need custom printers if you have fairly extreme printing needs (large or heavy paper, high-quality color, or large quantities)

And the typical large copier already stores lots of things on disk (http://catless.ncl.ac.uk/Risks/25.98.html#subj13)
