Low paper capacity for its price. Slightly below-par text and photo quality. Relatively high running costs. Wi-Fi not included (although available as an option).

OKI C612dn Review and Ratings

Decent print speeds ; Trim design ; Energy-efficient ; Highly expandable

Cost per page needs to drop ; So-so photo printing ; Small (but expandable) initial paper capacity ; Upgrades are pricey

The OKI C612dn’s print quality and speed make it a capable stand-alone printer for use in a small office or workgroup, and it’s small enough that it would work well as personal printer for an individual who needs to churn a high volume of color output...
