Format is the first thing that determines a device's class and price. Let's figure out what to choose.

When A4 Is Enough

  • Printing contracts, letters, invoices.
  • A small office with standard document flow.

When You Need A3

  • Drawings, plans, spread-page presentations.
  • Print production, layouts, large tables.

Conclusion

An A3 device also prints A4, but it costs more and takes up more space. Get A3 only if you genuinely need that format — otherwise you're overpaying.
