Overview

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.

Pros & Cons

👍 Pros

  • The black-on-white color combination delivers maximum contrast for text and barcodes, ensuring labels remain legible in variable lighting conditions across shelves, cables, bins, and equipment panels.
  • At approximately 9 meters per cartridge, the tape yield is sufficient for moderate-to-high labeling runs without frequent cartridge changes interrupting workflow.
  • The split-back liner design reduces peeling friction significantly — labels apply faster and cleaner than single-backing alternatives, particularly on high-volume jobs.
  • The hard plastic cartridge casing protects the tape from dust and humidity during storage, maintaining print quality consistency across the full tape length.

👎 Cons

  • Compatibility is restricted to four specific LW-series printers — the LK cartridge format is not cross-compatible with Epson's other label printer lines, limiting flexibility if you upgrade to a different model.
  • This is a single-use consumable with no refillable option — ongoing cost adds up in high-volume labeling environments compared to printers that accept larger roll media.
  • Standard adhesive is permanent, which is a limitation in environments where labels need to be repositioned or removed cleanly from sensitive surfaces.
  • The 1/2-inch tape width is fixed — users who need wider labels for richer text or larger print must purchase a different cartridge model.

Frequently Asked Questions

This cartridge is confirmed compatible with the LabelWorks LW-300, LW-400, LW-600P, and LW-700 printers. It uses the LK cartridge format — do not attempt to install it in older or newer Epson label printer lines that use a different cartridge format.
Each cartridge contains approximately 9 meters (just under 30 feet) of tape. At a typical label length of 1.5 inches, that yields roughly 70–80 labels per cartridge, though yield varies depending on the label length you configure.
The split-back liner is divided down the center, making the adhesive backing easier to peel cleanly without tools or frustration — particularly useful when labeling in volume or wearing gloves in a shop or lab environment.
This is a standard permanent-adhesion tape. The label is intended to stay adhered once applied. It is not a repositionable or removable variant.
No — this is a genuine Epson OEM cartridge. Third-party alternatives may vary in print consistency and adhesive performance; the OEM cartridge is formulated to Epson's specifications for consistent ink transfer and label durability in the LW series printers.
