Meanwhile, its superior function and easy operation make it your best choice among the

The 4B-2053A series printer provides thermal printing. The printing speed is
adjustable from 2.0, 3.0, 4.0, to 5.0 inches per second. It applies to a variety of printing
materials, including paper rolls, paper slices and fan-fold labels. In addition, the printer
has the built-in 1D and 2D barcodes that are commonly used, a TTF font and eight sets of
English numeric fonts in different sizes, and supports printing in 4 different directions.
And through the zoom function, the fonts can be enlarged. All these will enable you to
