Epson LK-4WBN LabelWorks 1/2" Black on White Standard Tape

The Epson LK-4WBN is the standard black-on-white 1/2-inch tape cartridge for the LabelWorks LW-300, LW-400, LW-600P, and LW-700 printer line. Black on white is the baseline labeling configuration for good reason — the contrast ratio is maximized for machine and human readability, whether you're tagging network cables in a rack, organizing storage bins, or marking assets in a school or office. Each cartridge delivers approximately 9 meters of tape, housed in a durable hard plastic shell that protects the roll from the humidity and dust that degrade tape quality over time in storage.

The practical engineering detail that separates the LK-4WBN from generic alternatives is Epson's split-back liner design: the backing is divided down its center length, which eliminates the fumbling and nail-digging that single-backing tape typically requires. In a workflow where you're printing and applying dozens of labels in sequence — cable management, inventory tagging, equipment labeling — the cumulative time saved is real. The cartridge drops into compatible LW-series printers without configuration; the printer identifies the tape width automatically. For users who depend on label consistency across a full cartridge run, the OEM formulation delivers it reliably in a way that third-party alternatives do not always match.
