Epson is kicking off 2025 with a major win. The company’s WorkForce Enterprise Series printers—the AM-C400 and AM-C550—have been awarded a perfect five-star rating by DataMaster Lab, a globally respected authority on office equipment testing.
Since 2009, DataMaster Lab has been evaluating printers under real-world conditions using internationally recognized standards. Their tests are known for being tough and thorough, especially when it comes to print quality, performance, and environmental impact. So when they hand out a five-star rating, it means a product truly stands out.
And stand out Epson did.
Built for performance, designed for efficiency
According to DataMaster Lab, the AM-C400 and AM-C550 proved to be exceptionally reliable and consistent throughout testing. These printers not only kept pace with demanding print jobs—they did so while consuming remarkably low energy, thanks to Epson’s Heat-Free Technology. That’s a win for both productivity and the planet.
Productivity was another area where these printers shined. Both models delivered 100% productivity in duplex mode, with 94% and 92% in workgroup mode—a rare feat in the A4 printer class. Even more impressive, they’re the first A4 models to feature Epson’s innovative C-shape paper path, allowing full-speed double-sided printing in a compact footprint.
Less energy, faster output, and a smaller footprint? That’s what modern offices are looking for.
If you’re tired of constantly changing toner or replacing parts, these printers are here to help. The AM-C400 required only one-third as many consumable changes compared to competitors, while the AM-C550 needed just half. That translates to less downtime, fewer disruptions, and lower operating costs.
DataMaster also praised the printers’ energy efficiency, with typical electrical consumption reported at around a third of that used by similar models—another testament to Epson’s commitment to eco-conscious design.
“We are thrilled to receive five-star reviews from DataMaster Lab for our WorkForce Enterprise AM-C400 and AM-C550 printers,” said Jester Cruz, Senior Regional Manager for Corporate Products at Epson Southeast Asia. “This recognition confirms our dedication to innovation, quality, and sustainability. Our Heat-Free Technology is changing the game, allowing businesses to be more productive while significantly reducing energy use and costs.”
With unmatched reliability, smart design, and industry-leading efficiency, the AM-C400 and AM-C550 aren’t just printers—they’re strategic business tools. Whether you’re focused on cutting costs, boosting performance, or achieving sustainability goals, these five-star printers deliver across the board.
