KYOCERA Develops World’s Smallest Thermal Printhead for Barcode Printing
New KMS Series is approximately 40% smaller and uses 20% less power
The new compact printhead structure is 40 percent smaller compared with conventional products, with a design to reduce resistance loss helping to save power. Through these advantages, the new KMS Series contributes to a compact design and the improved energy efficiency of portable printers.
KMS Series Thermal Printhead
Demand for portable printers for barcode shipping labels has expanded as logistic facilities such as warehouses and distribution centers’ volumes have increased globally, not only in developed economies but also in emerging Asian countries. With the need for compact sizes and a reduction in power consumption — since most printers in these facilities use portable batteries — there is an increasing demand for smaller, more energy-efficient printheads for use in next generation printers.
1. World’s smallest printhead for portable printers
In previous models, the driver IC was mounted on the ceramic substrate in the conventional structure. In the new design of the KMS Series, it is mounted on the circuit substrate. By changing the attachment method of the substrate and driver IC to wire bonding, the new product features a smaller depth of 9.9mm, reduced by approximately 40 percent from 16.3mm in conventional models. The new product yields the world’s smallest size among thin-film flat-type printheads, contributing to a smaller footprint and weight reduction of portable printers.

2. Contributes to energy saving
Because portable printers utilize batteries for operation, there is a need for better energy performance to reduce power consumption. By utilizing its technologies which have been cultivated over the years, Kyocera optimized the wiring layout to reduce resistance loss and improve the thermal efficiency of the heating element, thus reducing power consumption by up to 20 percent. With its enhanced thermal efficiency, the KMS Series improves the energy performance of portable printers contributing to longer battery life and higher work efficiency in label printing.
