If you are writing software to print to this printer and need a code snippet to send commands (TSPL/EPL), here is a standard C# feature example for printing a label via the driver:
Feature: Raw Text Printing (TSPL) This code sends raw TSPL commands to the Wincode C342 driver, allowing you to print barcodes and text without needing a complex label design software. If prompted by Windows Security, click "Install this
