Definition: A3 printer
An A3 printer — as the name suggests — prints on printer papers that have A3 paper dimensions, which measure 9.7 × 42 cm or 297 × 420 mm, which equals 11.7 × 16.5 in. A3 paper is part of the international paper size system and is double the size of the common A4 paper dimensions. However, an A3 printer doesn’t just specifically handle A3 paper, it can print on numerous sizes, including A4 paper, Tabloid and Ledger, also known as 11×17, and even postcards and envelopes.

Is it worth it?
Due to its price, an A3 printer is mostly worth it for big businesses that deal with contract-heavy printing, such as businesses in the legal and real estate fields. A3 printers, as well as many A4 printers, can do it all from printing, copying, and scanning to faxing documents; however, when it comes to finishes like automatic stapling, stacking, folding, and hole-punching, the A3 printer is a clear winner.
Overall, smaller offices or teams should invest in a high-quality A4 printer or use a professional online printing service instead, while big businesses can strongly benefit from investing in an A3 printer.
