foreword

Recently, I received a development task to call a thermal printer on the web to print and generate a barcode. The printer developed and used in this article is the Deli label printer DL-888D. Before development, you need to debug the printer, learn how to use the printer, and start development after printing with the printer's own program.

提示：其他打印同理，都可以按照教程进行开发

1. Two methods of front-end printing

1. Print directly from the browser

• Advantages: simple and convenient, just copy the code directly
• Disadvantages: cannot print directly, need to wake up a new window

2. Use third-party plugins
