To print certain special labels, specific configurations are needed when customizing the paper size in the print dialog box. Next, let's use a dual-row label as an example for illustration purposes. Its detailed configuration is as follows:
Label width: 20mm, Label height: 10mm 1 row, 2 columns
Issue
Originally, we would typically select a custom printing size of 42mm by 10mm. However, there are certain special labels that cannot be printed using this setup. In such cases, an alternative printing configuration is required. To get started, please refer to the diagram below.

Solution
The printer's recognized print range matches the one in the diagram. If you set the printing width to 42mm and the height to 25mm, the labels should print correctly. So, if the standard print settings don't work, consider using the diagram's configuration for printing.
