Honeywell / Datamax-O'Neil H-4212 Labels & Ribbons

The Honeywell / Datamax-O'Neil H-4212 does both. In thermal transfer mode it prints through a ribbon for durable, long-life labels; in direct thermal mode it prints straight onto heat-sensitive stock with no ribbon at all, which is how most shipping labels are produced.

The Honeywell / Datamax-O'Neil H-4212 takes thermal transfer ribbons up to 4.65" wide, up to 1,968 ft (600 m) long, on a 1" core, wound either coated side in or out. Wax suits coated paper labels, wax-resin handles synthetics and heavier handling, and full resin is the choice for chemical, solvent and outdoor exposure.

The Honeywell / Datamax-O'Neil H-4212 accepts media up to 4.65" wide, with a maximum print width of 4.16". Any narrower label will run as well, so long as the roll core and outside diameter also fit the media bay — width alone is not enough.

The Honeywell / Datamax-O'Neil H-4212 takes rolls on 3" cores, with a maximum roll diameter of 8". A roll on a larger core will not seat on the spindle, and one over the diameter limit will not let the cover close.

Yes. Because the Honeywell / Datamax-O'Neil H-4212 prints thermal transfer, it can image polypropylene, polyester and other synthetic facestocks that direct thermal printers cannot mark. Pair them with a wax-resin or full resin ribbon; wax will not anchor properly to a synthetic surface.

Yes — 4" × 6" sits inside this printer's media width, and it prints them as direct thermal with no ribbon, which is the standard setup for courier and marketplace labels.

Yes. The Honeywell / Datamax-O'Neil H-4212 accepts fan-folded stacks as well as rolls. A fanfold box holds far more labels than a roll of equivalent footprint, so it is the cheaper way to run high volume — the trade-off is bench space behind the printer.

Vantage Labels stocks blank thermal labels and printer ribbons that fit the Honeywell / Datamax-O'Neil H-4212, shipped from Canadian stock. Everything listed on this page has been checked against the printer's published media specifications — width, core, roll diameter and ribbon format — rather than matched on the printer's name.
