2026 A3 Office Printer Guide for Design and Technical Teams
Best Printer for Architecture & Engineering Office Australia 2026
Architecture and engineering offices often need more than an ordinary A4 printer. A3 plans, marked-up drawings, spreadsheets, schedules, tender documents and site packs are easier to review when printed at a larger size.
This guide focuses on A3 office multifunction printers for day-to-day technical documents. These machines are not replacements for dedicated A1 or A0 CAD plotters used for full-size construction drawings.
Quick Answer
For architecture and engineering teams that need A3 office printing and scanning, the Epson ET-16600 is the strongest all-round option in this guide because it combines A3 capability with refillable ink. The Brother MFC-J6957DW is better when paper capacity is the priority, while the Epson WF-7840 keeps upfront cost lower.

Price snapshot: 2 October 2026. Prices and availability can change. These are A3 office printers, not A1/A0 technical plotters.
1. Epson EcoTank Pro ET-16600
The ET-16600 prints up to A3+, scans and copies up to A3 and includes a 50-page two-sided ADF. Epson rates A4 print speed at 25 ISO ppm black and 12 ISO ppm colour.
Its refillable T542 ink system is attractive for offices producing regular colour markups and project documents, while the two 250-sheet cassettes allow A4 and A3 stocks to stay loaded.
2. Brother MFC-J6957DW
The MFC-J6957DW is ideal when several users share one A3 device. It supports two-sided print, scan, copy and fax up to A3 and provides three paper trays with up to 750 sheets plus a 100-sheet multipurpose tray.
3. Brother MFC-J6955DW
The MFC-J6955DW offers the same essential A3 office functions with two main paper trays rather than three. It remains a strong fit for a smaller architecture or engineering team that needs A3 but does not require the extra capacity of the J6957DW.
4. Epson WorkForce WF-7840
The WF-7840 is the budget-conscious A3 choice. It has dual 250-sheet cassettes, automatic duplex printing and an A3 flatbed scanner, making it useful as a secondary technical document printer or for smaller teams.
A3 Office Printer vs CAD Plotter
An A3 multifunction printer is ideal for reduced plans, markups, schedules and everyday project documents. If your team needs full-size A1 or A0 construction drawings, a dedicated wide-format plotter remains the correct category.

More Questions Buyers Ask
Can an A3 office printer print CAD drawings?
Yes for reduced-size review copies, markups and schedules that fit A3. For full-size A1 or A0 technical drawings, a wide-format CAD plotter is the correct category.
Is A3 scanning useful for architects and engineers?
Yes. It allows marked-up plans, schedules and larger documents to be digitised without first reducing them to A4.
Which is better for technical offices: EcoTank or INKvestment?
Both can suit A3 office work. EcoTank is attractive for refillable-ink economics, while Brother INKvestment models offer strong A3 office handling and large paper capacity. The better choice depends on volume and tray requirements.
Frequently Asked Questions
Is A3 large enough for architecture plans?
A3 is useful for reduced plans, markups and review copies. It is not a replacement for full-size A1 or A0 construction drawings.
Should an engineering office choose EcoTank or cartridge inkjet?
EcoTank is attractive for regular colour volume and lower ink cost. Cartridge-based business inkjet can have a lower upfront price and may suit lighter A3 requirements.
Why is A3 scanning useful?
It allows marked-up plans, schedules and larger physical documents to be digitised without reducing them to A4 first.
