What is an All in One Color Printer? | Three Machines in One

Walk into any small office and you’ll probably see one — a boxy unit that handles everything from a quick scan of a signed contract to a full-color brochure. For the self-employed, home-office worker, or small business, replacing four separate machines with one device cuts desk clutter and simplifies the workflow. But the term “all-in-one” doesn’t automatically mean color, and that’s where the confusion starts.

What Exactly Does an All-in-One Color Printer Do?

An all-in-one color printer — also called a multifunction printer (MFP) — performs four core tasks: printing, scanning, copying, and faxing. The “color” part means it uses multiple toner or ink cartridges (Cyan, Magenta, Yellow, and Black) to produce full-spectrum output, unlike monochrome models that only print in black and white.

Most models also include a document feeder for batch scanning or copying, a flatbed scanner for books or thick items, and wireless connectivity so everyone on the network can send jobs from their desk or phone.

The Two Main Technologies: Inkjet vs. Laser

The choice between inkjet and laser comes down to volume and what you print. Inkjets like the Epson EcoTank series produce vibrant photos and handle mixed document types well, making them the better fit for home offices with lighter printing. Lasers like the Brother MFC-L3780CDW deliver sharp text, faster speeds, and lower per-page costs for offices that print daily.

Here’s how the leading 2026 models stack up across the specs that matter most:

The purchase price is only half the story. The ongoing cost of toner or ink determines whether the machine saves or costs you money over a year. Monochrome laser pages run about 3 cents each. Color laser pages jump to roughly 12 to 15 cents per page, according to Wirecutter’s 2026 estimates. Inkjet prices vary more, but tank-based systems like the EcoTank bring color pages well below 2 cents with the included bottles.

High-yield toner cartridges for the Brother MFC-L3780CDW illustrate the spread: black cartridges yield about 5,500 pages, while the color cyan, magenta, and yellow cartridges yield about 4,500 each. Standard cartridges cut those numbers by more than half, so always check the page yield before buying replacements.

Key Features That Matter in 2026

Modern all-in-one color printers add more than just basic functions. Automatic duplex (two-sided) printing is standard on most, but duplex scanning is rarer — PCMag notes that many laser models handle simplex scanning far better than two-sided jobs. Cloud faxing replaces physical phone lines on newer units, a cost saving that also makes setup easier through the manufacturer’s app. Wi-Fi, Ethernet, and USB connections come standard, and some professional models add security features like encrypted data paths.

What Most Buyers Get Wrong

The biggest mistake is assuming every all-in-one printer prints in color. Some models are identical in shape and features but monochrome-only — you have to verify the “color” spec in the product description. The second mistake is ignoring page yield on the standard toner cartridge that ships with the printer. Color toners often run out before you expect them. And if your office relies on old-style phone-line faxing, check for a physical fax port before buying.

Choosing the Right Machine for Your Setup

A small business printing 500 color pages a month will reach cost parity faster with a laser model like the Brother MFC-L3780CDW. A home office that prints a mix of photos and documents will find the Epson EcoTank ET-2400 a strong budget pick. For high-volume offices, the Brother MFC-L8930CDW handles heavy workloads without slowing down. Whichever route you take, grab a unit that supports your current OS version — Windows 11 and macOS 15 are the baseline for driver support in 2026.
