Brother TD-4550DNWB Labels & Ribbons

The Brother TD-4550DNWB is direct thermal only. It applies heat directly to heat-sensitive label stock, so labels are the single consumable — there is no ribbon to buy or replace.

None. The Brother TD-4550DNWB is a direct thermal printer, so there is no ribbon — it images heat-sensitive labels directly. If print on your labels fades in heat or sunlight, that is the direct thermal stock behaving normally, not a printer fault.

The Brother TD-4550DNWB accepts media up to 4.65" wide, with a maximum print width of 4.27". 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 Brother TD-4550DNWB takes rolls on 0.5" / 1" / 1.5" cores, with a maximum roll diameter of 5". A roll on a larger core will not seat on the spindle, and one over the diameter limit will not let the cover close.

Three things stop a roll loading in this printer: the roll is over 5" in diameter; the core is not 0.5" / 1" / 1.5". Label width is usually the first thing people check and the least likely culprit — core size is the common one.

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.

Vantage Labels stocks blank thermal labels that fit the Brother TD-4550DNWB, 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.
