Wasp 633808402921 Direct Thermal Paper Label 2x1

Overview

The Wasp 633808402921 is a direct thermal label consumable: 2-inch by 1-inch paper stock, 5560 labels per roll, 8-inch outer diameter, supplied in a 4-pack. Direct thermal paper requires no ribbon — heat from the printer head darkens the label surface during printing. This format is standard for logistics, inventory tagging, shipping labels, and asset barcoding in warehouse and retail environments where print volume is high and ribbon supply chain complexity must be avoided.

Compatibility

These labels are designed for Wasp direct thermal printers (including models in the WPL and WLS series) that accept 8-inch-OD rolls. Confirm your printer's label width tolerance (2 inches) and thermal head specification before ordering. Not compatible with thermal transfer printers or inkjet systems. If your printer requires a different roll diameter, core size, or label dimension, verify the model number on your device's specification sheet.

Installation Notes

Direct thermal labels are sensitive to heat, light, and moisture. Store rolls in a cool, dry environment (below 75°F, 65% relative humidity or lower) to preserve print darkness and readability over the label's shelf life. Once loaded into the printer, feed the label roll according to your device's threading guide — improper tension can cause misalignment or jams. Each roll contains approximately 5560 printable labels; plan replenishment cycles based on your daily print volume to avoid downtime.
