As mobile operations become increasingly important in retail, logistics, warehousing and field services, businesses need printing solutions that are compact, flexible and easy to deploy. The SPRT SP-L39 mobile label printer combines a lightweight design, adjustable 40mm–80mm paper width, wireless connectivity and a 2600mAh rechargeable battery in a compact device. Designed for both receipt and label printing, it provides a versatile mobile printing solution for businesses that need to print wherever work happens.
One of the key advantages of the SP-L39 is its adjustable paper holder, supporting media widths from 40mm to 80mm. Instead of being limited to a single paper size, users can adjust the media width according to different printing requirements. This makes the SP-L39 suitable for a variety of applications, including product labels, logistics labels, price labels, serial number labels, receipts and other business documents.
The printer supports a maximum paper roll diameter of 50mm, while its easy-loading design helps simplify media replacement during daily operation.
The SP-L39 uses direct thermal printing technology, eliminating the need for ink, toner or ribbons. With a print resolution of 203 dpi and a print speed of up to 80mm/s, it delivers clear and efficient printing for everyday mobile applications. It supports for ESC/POS, CPCL and TSPL command sets, which makes the SP-L39 suitable for different receipt and label printing environments, providing greater flexibility for system integration.
A mobile printer should be easy to carry without adding unnecessary weight to daily operations.
Measuring just 113mm×105mm×60mm and weighing approximately 376g without paper, the SP-L39 features a compact form factor designed for portable use.
Whether carried between warehouse aisles, used at a retail counter or taken into the field, its compact design makes mobile printing more convenient for workers who need to move throughout the day.
The SP-L39 is equipped with a 2600mAh rechargeable Li-ion battery, providing the power needed for mobile printing applications. Long battery life helps reduce frequent charging and allows employees to stay productive when working away from a fixed power source. A battery status reminder function also helps users monitor remaining power and better manage daily printing tasks.
The SP-L39 supports Type-C and Bluetooth connectivity, with Wi-Fi available as an option. Bluetooth connectivity makes it convenient to pair the printer with compatible mobile terminals, while optional Wi-Fi provides additional flexibility for wireless printing environments.
It also supports Windows, Android and iOS, making it easier to integrate the printer into different mobile workflows and business systems.
In addition to its compact design and flexible media handling, the SP-L39 includes several functions designed to support reliable everyday operation. Features such as paper-out detection, label mark detection and overheat protection help users monitor printer status and reduce interruptions during printing.
A built-in display provides visible printing status and setting information, helping operators check the printer during mobile use.
