Wasp 633808403225 4x2 Direct Thermal Paper Labels

Overview

The Wasp 633808403225 is a direct thermal paper label stock sized 4 inches wide by 2 inches tall, supplied in 1250-label rolls on a 5-inch outer diameter spool. These labels address the core need in warehouse, retail, and shipping operations: on-demand label printing without thermal-transfer ribbon cost or complexity. Direct thermal media darkens under heat alone, eliminating the ribbon supply chain and reducing consumable overhead per label printed.

Compatibility

Direct thermal labels work with Wasp thermal printers and any third-party direct thermal printer (industrial or desktop) that accepts 4x2 media on standard 1-inch or 1.5-inch core spindles. The 5-inch OD roll profile matches most commercial label printer trays. Verify your printer's media-width and label-length specifications before ordering — some desktop printers top out at 3-inch-wide stock.

Installation Notes

Load the roll into your printer's label-feed mechanism with the thermal-sensitive side facing the printhead. The 1250-label count per roll translates to roughly 20–25 feet of continuous stock depending on gap height and print density settings. Store in cool, dry conditions (below 25°C and 60% relative humidity) to prevent premature darkening and adhesive degradation. Direct thermal stock is light-sensitive; keep rolls in their protective packaging until use.
