More DPI Means More Detail

Thermal printheads create images using rows of heated dots. The number of dots packed into each inch determines the level of detail the printer can reproduce. Choosing the right resolution helps ensure your text is readable, your barcodes scan reliably and your labels look the way they should.

Standard Resolution

203 DPI

A dependable choice for standard shipping labels, larger barcodes and general-purpose thermal printing.

Versatile Resolution

300 DPI

A versatile option for smaller text, average-sized barcodes and many product, asset and shipping labels.

High Resolution

600 DPI

Designed for highly detailed labels where very small text, barcodes and fine graphics require additional precision.

Small asset and product labels
Very small text and detailed barcodes
Synthetic materials with appropriate ribbon selection

DPI Isn't the Only Factor

Print resolution is important, but the printer, ribbon, label material, print speed and temperature settings can all affect the final result. Your complete print setup should be considered when selecting a thermal printer.
