TSC’s Most Versatile Compact Light Industrial Label Printer

The TSC MB Series of industrial thermal label printers is a new value leader for 4-inch wide light industrial label printing. The MB series is designed to fit in alongside bigger TSC industrial printer models including the MH241 and MX241P Series. The MB240 features a small footprint, easily understood operator interface and a full set of options to meet nearly every printing application.

Its compact design, quiet operation and fast label throughput is equally at home in the office or shop floor. The printer’s all-metal construction and die-cast aluminum print mechanism engine is durable enough to withstand the toughest production environments and is designed for years of trouble free use.

Smart Colorful Display Version

The new MB240T comes with an easy to use high-contrast 3.5-inch color touch LCD panel with 6 buttons. Common tasks such as label calibration are one touch away. Menus can be customized to bring frequently used tasks to the front screen for faster, less complicated operation.

Enhanced Print Quality

The MB Series 4-inch industrial printers feature the best print quality TSC offers thanks to faster processors and upgraded firmware. We call our enhanced print quality “Thermal Smart Control” which tracks and precisely calculates the duration that each pixel needs to be heated to provide accurate, crisp and clear labels every time, whether you are printing one label at a time or thousands of labels in a batch.

Available in both 203 dpi and 300 dpi resolutions for a wide range of applications

The MB Series can print on a wide variety of labels, ranging from healthcare patient safety, electronics and jewelry labeling to shipping and distribution labels, making it ideal for industrial duty printing.

Communications to meet your needs

Connect to any host with a variety of interfaces including Ethernet, USB, USB-Host, Serial RS232 or optional 802.11 a/b/g/n wireless or Bluetooth. There is also an optional General Purpose Input/Output (GPIO) interface for connection to a variety of industrial and label application equipment.

Options including Label Peel, Present Sensor and Internal Rewind

The MB series can be equipped with an optional Peel, Present and Internal Rewind that peels the label as it exits the printer and waits for the user to take the label until printing the next label. The backing waste is conveniently taken up inside the printer on an internal rewinder. Other options include cutters, Peel and Present, GPIO and wireless 802.11 a/b/g/n and Bluetooth communications.

Powerful TSPL-EZD printer programming language

The MB series features TSPL-EZD firmware that is easy to set up and use. TSPL-EZD offers a fully compatible set of standard industry emulations, including Line Mode, Datamax®, Eltron® and Zebra® languages and will work in many IT environments including Oracle, Unix, AS/400, Windows, Stand Alone, and many more.

The included DiagTool configuration software makes it a snap to replace existing printers with a modern durable MB Series printer. Other TSPL-EZ features include a file manager and programming language that support stand-alone and down-time programming solutions allowing you to print labels without connection to a host computer, or optionally be able to continue printing labels during times of network failure.
