The Epson LabelWorks LW-400 is a portable electronic label maker designed for professionals who need reliable, on-the-spot labeling across office, facilities management, manufacturing, and light industrial environments. It prints durable laminated labels in widths of 4 mm, 6 mm, 9 mm, 12 mm, and 18 mm, supporting a broad range of labeling tasks from cable identification and asset tagging to folder tabs and general signage. The LW-400 supports multiple barcode formats — including CODE39, CODE128, ITF, CODABAR, UPC-A, UPC-E, EAN-8, and EAN-13 — making it a practical choice wherever scannable labels are required. A backlit LCD display aids visibility in low-light conditions, while the compact footprint and battery or AC adapter power options keep the device ready to use in any workspace.
