Method and System for Reducing Latency in Printing of Receipts by Print Head Geometry Optimization

Fig. 1 illustrates a general arrangement of print heads in a dual print head thermal printer. Generally, when a paper, for example, receipt, is printed on the dual print head thermal printer with one print head on either side of the paper, blank spaces are left on the paper. This phenomenon of the blank spaces being left on the paper while printing is also called printing latency. The printing latency in thermal printers with dual print heads is because of the distance between a lower print head and an upper print head and the upper print head and a cutter, as depicted in fig. 1.

Figure 1

Disclosed is a method and system for reducing latency in printing of receipts by print head geometry optimization.

The method and system disclosed herein includes arranging print heads of a dual print head thermal printer by optimizing spacing between the print heads to reduce length of a paper to be printed and blank spaces left on the paper while printing.

Fig. 2 illustrates the dual print head thermal printer with optimized positioning of the print heads in accordance with the method and system disclosed herein. The distance between the upper print head and the lower print head is optimized. Further, the distance between the upper print head and the cutter is also optimized to minimize printing latency while p...
