Thermal Transfer Label Printer

The TSC TTP-345 is a desktop barcode and label printer built for shipping, inventory and retail labelling. It supports both thermal transfer and direct thermal methods. Connectivity includes USB, serial and Ethernet ports for integration with existing point-of-sale or warehouse systems.

300 dpi Print Resolution

This model prints at 300 dpi, producing 12 dots per millimetre for sharp barcodes, small text and graphics on labels up to 108 mm wide. The 300 dpi resolution is the specification that determines whether the printer meets your label clarity requirements.

4MB Flash and 5-Inch Roll Capacity

The 4MB Flash memory stores fonts, graphics and label formats locally. The printer accepts label rolls up to 127 mm outer diameter, reducing roll changes during high-volume print runs. It replaces the earlier 99127A02700LF part number.
