Searching for the best A3 multifunction printer in Australia usually turns up ranked lists of SOHO (Small office, Home Office) desktop inkjets. For an office that prints every day, those lists answer the wrong question. The machine that suits a home study and the machine that suits twenty people sharing one device have almost nothing in common beyond the paper size.
A better approach is to work out what you actually need, then judge devices on the numbers that drive cost and reliability over several years. Below we cover whether you need A3 at all, how to read cost per page when choosing an A3 Multifunction Printer, the specifications that matter, and when buying SOHO beats a serviced agreement.
Do You Actually Need A3?
A3 devices cost more to buy, take up more floor space and often cost more to run. They earn their place when the larger format is genuinely part of the work.
A3 is usually worth it when you
- Produce plans, drawings, maps or site documents
- Print posters, menus, signage or display material in house
- Create booklets, where A3 folds to A4
- Need to copy or scan large originals, not just print them
- Run enough volume that a sturdier machine lasts longer than a desktop one
Watch the scanning trap
Plenty of devices in the “Small or Home office” (SOHO) segment advertised as A3 will print A3 but only scan or copy A4, because the document feeder is A4 sized. If copying large originals is part of why you are buying, confirm the feeder and glass handle A3 before anything else. It is the single most common disappointment with A3 purchases.
How to Read Cost Per Page Honestly
Cost per page is the number that decides what a device really costs you, and it is also the number most often misunderstood.
The five percent problem
Published yields come from standardised test methods rather than from your documents. For mono toner, the test page sits at about five percent coverage, which is roughly plain text with plenty of white space. Colour and inkjet yields use a suite of test pages averaging around five percent per colour, so the arithmetic differs again.
Either way, a page carrying a chart, a photograph or a dark header uses considerably more than the test page, so your real cost per page lands above the quoted figure. Use quoted numbers to compare devices against each other, never to build a budget.
The consumables nobody quotes
Toner is the visible cost. The expensive surprises are the parts behind it, and which ones apply depends on the model.
- Drums, which wear on a page count of their own
- Fusers, which bond toner to paper and eventually fail
- Transfer belts on colour devices
- Maintenance kits, bundled replacements due at set intervals
- Waste toner containers on larger machines
On a cheap device, one of these can cost close to a replacement machine. On a business device under a service agreement, they are usually included, which is a large part of why the two look so different on paper and so similar in the bank account.
Why all-in-one cartridges cost more
Some devices combine toner and the imaging drum in a single cartridge, so you pay for imaging components every time the toner runs out. Others keep them separate, so you replace a toner bottle often and a drum rarely. Office devices more commonly use the separated design, and toner yields in that class can reach around ten thousand pages, though figures vary widely by model and some small office printers use separate drums too.
Worth knowing that consumables are a major and recurring revenue stream for printer manufacturers, which is why a low purchase price tells you very little about what a device costs to own. Ask for the yields and the part prices, not just the sticker.
Which Specifications Actually Matter?
Ignore the marketing superlatives when comparing A3 office printers and look at six numbers.
| Specification | Why it matters | What to ask |
| Recommended monthly volume | Duty cycle is a ceiling rather than a target, and sustained heavy use accelerates wear | What volume is this built for, not its maximum? |
| Cost per page, mono and colour | Colour commonly runs two to five times mono and can get up to ten times easily, depending on the model | What are both rates, and at what coverage? |
| Paper capacity and trays | Determines how often someone reloads, and which stocks you can keep ready | How many sheets, across how many trays? |
| Document feeder size and duplex scanning | Decides whether you can copy A3 and scan double-sided in one pass | Does the feeder take A3, and scan both sides? |
| Finishing options | Stapling, hole punching and booklets save manual work | Which options fit this model, and at what cost? |
| Security and authentication | Shared devices hold documents and sit on your network, and secure release keeps jobs from sitting in the tray | Does it support user authentication and secure release? |
Match the device to how you print
Two offices printing the same number of pages can see different costs. Heavy colour coverage is the main reason, and on inkjet devices start-up and head cleaning consume ink as well, so occasional short jobs spread that overhead across fewer pages. Honest sizing uses your actual meter readings and your real job mix, which is also what any supplier should quote against. Our guide on which colour printer suits your business helps work out how much colour you genuinely need.
Buy Outright or Take a Serviced Agreement?
Both make sense in different situations, and the honest answer depends on volume and who carries the maintenance.
| Buying SOHO outright suits | A serviced agreement suits |
| Low volume, perhaps a few hundred pages a month | Daily shared use across a team |
| Offices comfortable sourcing their own consumables | Offices with nobody to chase parts and toner |
| Simple needs with little finishing | Finishing, scanning workflows and integration |
| Capital available and a tolerance for repair bills | A preference for predictable monthly costs |
The question that settles it
Ask who replaces the fuser at nine in the morning when a deadline is due. If the answer is an office manager with other work to do, a service agreement earns its keep. If your volume is genuinely low and the device is simple, buying can be the better deal. Our breakdown of office printer leasing costs gives a sense of the numbers, and printer support covers what servicing includes.
A Practical Shortlist Process
Four steps will get you a comparable set of quotes rather than a pile of brochures.
- Measure. Pull meter readings across several months where you can, ideally a year, split by colour and mono, and note your busiest month plus any growth you expect. Two readings a month apart is a starting point, but it can miss seasonal peaks.
- Define the format needs. How often you print A3, whether you copy or scan A3, and which paper stocks you use.
- List the must-haves. Finishing, authentication, tray capacity, scanning workflow and anything your software requires.
- Quote against that brief. Ask every supplier to price the same volumes and inclusions so the comparison is real.

What The Specifications Confirm
Reliable to plan around
- Yield figures come from standardised low-coverage test pages, so your documents will cost more per page than the brochure suggests.
- Laser devices need drums, fusers, transfer belts and maintenance kits at intervals, and which parts apply depends on the model.
- Some A3 printers scan and copy only A4, so check the scanner and feeder sizes separately from the print size.
- Colour commonly costs a few times more per page than mono, which makes it worth controlling rather than assuming.
Worth checking model by model
- Toner and drum yields vary widely, and separated designs are not exclusive to business machines, so compare the actual figures.
- Duty cycle is published inconsistently across manufacturers, and not every device lists a separate recommended monthly volume.
- Booklet making and other finishing usually depends on optional units rather than coming as standard.
What To Do Next
Pull your page counts, decide how much A3 you really print, and write down the finishing and scanning you need. That single page turns a vague search for the best device into a straightforward comparison.

Browse the multifunction device range, look at printer renting, whether you would rather have servicing included, or rent a multifunction printer on terms that suit your volume. Smaller teams may find our guidance on small business multifunction printers a better starting point.
Key Takeaways
There is no single best A3 multifunction printer, only the one that matches your volume, your format needs and your tolerance for maintenance. Confirm the device scans A3 and not just prints it, treat quoted cost per page as a best, but unrealistic case measured at five percent coverage, and ask what the drums, fuser and maintenance kits cost before you compare purchase prices. Size the machine to your measured volume rather than its maximum, and let your real numbers decide.
