TDK LS5402K Printhead

TDK LS5402K Printhead is a 304 dpi thermal printhead built for the Astro-Med QuickLabel System QLS-4000 Color Label Printer. Rated for label media up to 130 mm wide, it delivers the high-resolution output required for colorful branding and small-format labels. This listing describes the unit as a used surplus stock; it is compatible specifically with the QLS-4000, and some sellers note that it may not be covered by the original manufacturer’s warranty or offered through an authorized distributor. The LS5402K serves as a replacement component to restore print quality when the existing printhead shows wear, enabling reliable color label printing across applications such as product identification, barcoding, and batch coding in retail, healthcare, or manufacturing environments that utilize 304 dpi color labeling.
