About package

This repository uses a module that communicates with the printer port.

This module is rewritten based on a module on github and it has removed features such as: print qrcode, print barcode, print images.

Link module github: https://github.com/song940/node-escpos

New features in this module:

• Fixed the width of the paper size when changing font size.
• Determining the number of bytes of letters with different types of letters prevents overflow on the line.
• Auto line break by space in table, auto line break for words with too long character count.
• Reconstructing table is simpler and won't break when changing character type and font size.

Primary file of module: ./index.js;

Libraries inside module:

• Class Printer - Make a printer driver to send data to device.
• Class Printer.Serial - Make a device via Serial port.
• Class Printer.USB - Make a device via USB port.
• Property Printer.Chars - Contains special characters of printer.

Sometime delay

I search for solutions myself and find the libraries that people share to combine or rewrite as I desire.

So sometimes I often stop a project to code what I need.

If you want me to develop additional code, leave an issue with your wishes I will try to code
