## Long description

Compatible label tape Brother TZe-421 9 mm x 8 m black on red is a replacement cassette for Brother label printers that produces durable adhesive labels with black text on a red background. The tape is 9 mm wide and 8 m long, suitable for a variety of marking tasks such as signage, filing, cable identification and asset labelling. It is designed to fit devices that accept TZe-type cartridges and to deliver clear, high-contrast printing for easy reading and long-term use.
Advantages
This compatible Brother TZe-421 tape delivers consistent print quality with sharp black characters on a vivid red substrate, enhancing visibility for warnings, tags and identification labels. The adhesive backing provides reliable attachment to smooth and semi-textured surfaces, while the laminated surface resists smudging, light wear and routine cleaning. The 9 mm width balances readability and compact label size, and the 8-meter length reduces the frequency of cartridge changes in medium-use environments.
Suitable for
Office filing and shelf labeling
Cable and wire marking in IT and electrical installations
Equipment and asset identification in warehouses and workplaces
Safety and warning labels where high-contrast red background improves visibility

How to use
Turn off the label printer before replacing the cassette, open the cassette compartment, and remove the empty cartridge. Insert the compatible TZe-421 cassette according to the device manufacturer’s guidance, making sure the tape feeds correctly through the printer’s outlet. Close the compartment, power on the printer and run a test print or alignment if required. Use the printer software or built-in keyboard to design labels with appropriate font size and margins for the 9 mm width.
Usage recommendations
For best adhesion, apply labels to clean, dry surfaces at room temperature. Avoid placing labels on highly textured, oily or low-energy plastics without testing first. When labelling cables or rounded surfaces, press firmly along the length of the label to ensure full contact. Store unused cassettes in a cool, dry place away from direct sunlight to preserve adhesive performance and colour fidelity.
