Front-end thermal printing: an effective solution to the garbled problem

Front-end thermal printing functions are very common in actual development, but character encoding problems often plague developers. Recently, a developer encountered a garbled problem when printing tickets using print-js. Various solutions on the Internet, such as adjusting character encoding or using electron, have not worked.

Ultimately, the developer discovered that the root cause of the problem was not character encoding, but the wrong printer driver. The driver version provided by the customer is incorrect, resulting in garbled codes for both browser and WPS printing. Only the driver's own test printing function is normal.

After replacing the driver, the problem is solved. This case reminds us:

1. Pay attention to official documents: read the equipment manual carefully, this is the most reliable operating guide.
2. Verify customer information: The information provided by the customer may be biased or outdated and needs to be carefully verified.
3. Official channel priority: The official website is the best way to get the latest drivers and technical support.

Therefore, it is crucial to properly install and configure the driver in front-end thermal printing. When encountering problems, systematically troubleshoot and seek official support can often find the most effective solution.
