E-Class Mark III Barcode Printers

The Datamax-O'Neil E-Class Mark III has reached end of life.

This product replaces the older Datamax-O'Neil E-Class.

The Datamax-O'Neil E-Class Mark III offers versatility previously unseen in the E-Class series. Available in four distinct models, the E-Class Mark III meets the needs of any desktop printing operation. A 4" wide maximum print width is ideal for shipping label printing, while still maintaining support for smaller labels, such as on prescription bottles or retail inventory.

The E-Class Mark III prints at up to 6 inches per second, quick enough to keep up with demanding print jobs, and prints as direct thermal or thermal transfer depending on your labeling needs. With a larger media roll capacity and a rugged design, the Datamax-O'Neil E-Class Mark III is the ideal desktop printer for maximizing uptime.

• Clear media window makes level checks a snap
• 203 dpi and 300 dpi models available
• Serial, USB standard, Parallel, Ethernet available
• Adjustable media sensor on Professional models

Datamax-O'Neil E-Class Mark III Reviews

POSGuys Rating:

Some unique features of the E-Class Mark III are it's end user replaceable platen roller and printhead. Both of these modules are easily removed and replaced by hand, no service calls just order the part and swap it out. The printheads for the E-Class Mark III are not backwards compatible with the old E-Class models but they do cost about half as much so it is worth the upgrade if you are ready to make the switch.
