node silent print to themral

To perform silent printing to a thermal printer using Node.js, you can follow these steps:

  1. Install the necessary dependencies:
  2. First, ensure that you have Node.js installed on your system.
  3. Open your command line interface (CLI) and navigate to your project directory.
  4. Run the following command to initialize a new Node.js project: npm init -y
  5. Next, install the node-thermal-printer library by running the following command: npm install node-thermal-printer

  6. Import the necessary modules:

  7. In your JavaScript file, import the node-thermal-printer module: javascript const ThermalPrinter = require('node-thermal-printer');

  8. Configure the printer:

  9. Create a new instance of the ThermalPrinter class: javascript const printer = new ThermalPrinter({ type: 'epson', interface: 'printer:your_printer_name', options: { timeout: 5000, }, }); Replace 'your_printer_name' with the name of your thermal printer.

  10. Set the printer options:

  11. Configure the necessary options for your printer, such as character set, font size, and alignment. Refer to the printer's documentation for the available options.
  12. For example, to set the character set to 'SLOVENIA', font size to 'small', and alignment to 'center', you can use the following code: javascript printer.setCharacterSet('SLOVENIA'); printer.setTextSize('small'); printer.alignCenter();

  13. Add content to the printout:

  14. Use the various methods provided by the ThermalPrinter class to add text, images, or barcodes to the printout.
  15. For example, to add text, you can use the printer.print method: javascript printer.print('Hello, world!');

  16. Perform the silent printing:

  17. To perform the silent printing, call the printer.execute method: javascript printer.execute() .then(() => { console.log('Print successful!'); }) .catch((error) => { console.error('Error:', error); });
