Label tape Brother M-K231 12 mm x 8 m black on white replacement

Replacement label tape compatible with Brother label printers in the M-K231 format, 12 mm wide and 8 m long, with black print on white backing. This label tape is designed to produce clear, high-contrast text and simple symbols for cable marking, shelf labeling, file identification and general equipment tagging. The 12 mm width fits commonly used handheld and desktop Brother label printers that accept M-K series cartridges, offering a balance between readable text and compact label size.

Advantages

The tape produces legible, high-contrast black-on-white labels that remain easy to read in typical office, home, and light industrial environments. The 8 m roll length provides multiple labels per cartridge, reducing the need for frequent replacements. The self-adhesive backing ensures secure attachment to flat surfaces such as plastic, metal and cardboard, while the printable surface resists smudging under normal handling. Compatible format and width allow straightforward installation into compatible Brother printers without adjustments.

How to use

Install the cartridge into a compatible Brother label printer according to the printer manual. Create the desired text, symbols or barcodes using the printer controls or supported software, then print at the recommended settings for 12 mm tape. Cut or peel the label from the liner and apply to clean, dry surfaces, pressing firmly along the length of the label to ensure adhesion. For best results, avoid applying to surfaces with heavy texture, dust or oils.

Usage recommendations

Store unused rolls in a cool, dry place away from direct sunlight. For long-lasting legibility, apply labels to clean surfaces and smooth areas; avoid placing labels on surfaces that are frequently exposed to abrasion, solvents or extreme temperatures. Replace rolls when print clarity diminishes or the adhesive weakens.
