Various iDPRT SP420 Labels & Ribbons

The Various iDPRT SP420 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 Various iDPRT SP420 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 Various iDPRT SP420 accepts media up to 4.3" wide, with a maximum print width of 4.09". 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 Various iDPRT SP420 takes rolls on 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.

Yes. The Various iDPRT SP420 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.

No. The Various iDPRT SP420 takes 1" / 1.5" cores. A 3" core roll — the usual industrial format — will not fit its spindle, so check the core before ordering, not just the label size.

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

Vantage Labels stocks blank thermal labels that fit the Various iDPRT SP420, 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.
