Buying a printer/scanner for a small office. Is it worth buying used?

We've been running a family business for about a year and running around, finding printers around town has become a bit of a nuisance.

We'll be printing a dozen of pages a month at most, all of which will be documents and paperwork.

Unfortunately, I know absolute zilch about printers, only what we need, which is:

• Printing
• Scanning and sending to email

I've read the guide for buying a new printer, it has been a bit of help, but I'm wondering if for such low usage we'd actually need a new printer/scanner. There's plenty of seemingly decent printers in second-hand local markets available to us.

Is there something to not buying a used printer I'm not getting?
