Node Thermal Printer
Node.js module for EPSON and STAR thermal printers command line printing.
Installation
$ npm install node-thermal-printerLinux specific
Linux requires build-essentials
sudo apt-get install build-essentialFeatures
const ThermalPrinter = require("../node-thermal-printer").printer;
const PrinterTypes = require("../node-thermal-printer").types;
let printer = new ThermalPrinter({
type: PrinterTypes.STAR, // Printer type: 'star' or 'epson'
interface: 'tcp://xxx.xxx.xxx.xxx', // Printer interface
characterSet: 'SLOVENIA', // Printer character set - default: SLOVENIA
removeSpecialCharacters: false, // Removes special characters - default: false
lineCharacter: "=", // Set character for lines - default: "-"
options:{ // Additional options
timeout: 5000 // Connection timeout (ms) [applicable only for network printers] - default: 3000
}
});
let isConnected = await printer.isPrinterConnected(); // Check if printer is connected, return bool of status
let execute = await printer.execute(); // Executes all the commands. Returns success or throws error
let raw = await printer.raw(Buffer.from("Hello world")); // Print instantly. Returns success or throws error
printer.print("Hello World"); // Append text
printer.println("Hello World"); // Append text with new line
printer.openCashDrawer(); // Kick the cash drawer
printer.cut(); // Cuts the paper (if printer only supports one mode use this)
printer.partialCut(); // Cuts the paper leaving a small bridge in middle (if printer supports multiple cut modes)
printer.beep(); // Sound internal beeper/buzzer (if available)
printer.upsideDown(true); // Content is printed upside down (rotated 180 degrees)
printer.setCharacterSet("SLOVENIA"); // Set character set - default set on init
printer.bold(true); // Set text bold
printer.invert(true); // Background/text color inversion
printer.underline(true); // Underline text (1 dot thickness)

printer.setTypeFontA(); // Set font type to A (default)
printer.setTypeFontB(); // Set font type to B
printer.setTextNormal(); // Set text to normal
printer.setTextDoubleHeight(); // Set text to double height
printer.setTextDoubleWidth(); // Set text to double width
printer.setTextQuadArea(); // Set text to quad area
printer.setTextSize(7,7); // Set text height (0-7) and width (0-7)
printer.leftRight("Left", "Right"); // Prints text left and right
printer.table(["One", "Two", "Three"]); // Prints table equaly
printer.tableCustom([ // Prints table with custom settings (text, align, width, cols, bold)

{ text:"Center", align:"CENTER", width:0.25, bold:true },
{ text:"Right", align:"RIGHT", cols:8 }
]);
printer.code128("Code128"); // Print code128 bar code
printer.printQR("QR CODE"); // Print QR code
await printer.printImage('./assets/olaii-logo-black.png'); // Print PNG image
print.clear(); // Clears printText value
print.getText(); // Returns printer buffer string value
print.getBuffer(); // Returns printer buffer
print.setBuffer(newBuffer); // Set the printer buffer to a copy of newBuffer
print.getWidth(); // Get number of characters in one lineInterace options

| tcp://192.168.0.99:9100 | Network printer with port |

| printer:My Printer Name | Select system printer by name via Printer or Electron printer module module |

System Printer Drivers
When using a system printer, you need to provide the driver. Use electron-printer or printer driver:
const ThermalPrinter = require("../node-thermal-printer").printer;
const PrinterTypes = require("../node-thermal-printer").types;
const electron = typeof process !== 'undefined' && process.versions && !!process.versions.electron;
let printer = new ThermalPrinter({
type: PrinterTypes.EPSON',
interface: 'printer:My Printer',
driver: require(electron ? 'electron-printer' : 'printer')
});Use a custom printer driver:
const ThermalPrinter = require("../node-thermal-printer").printer;
const PrinterTypes = require("../node-thermal-printer").types;
let printer = new ThermalPrinter({
type: PrinterTypes.EPSON',
interface: 'printer:My Printer',
driver: MyCustomDriver
});
// you can also set the driver after init:
printer.setPrinterDriver(MyCustomDriver)
### Example
```js
const ThermalPrinter = require("../node-thermal-printer").printer;
const PrinterTypes = require("../node-thermal-printer").types;
let printer = new ThermalPrinter({
type: PrinterTypes.EPSON,
interface: 'tcp://xxx.xxx.xxx.xxx'
});
printer.alignCenter();
printer.println("Hello world");
await printer.printImage('./assets/olaii-logo-black.png')
printer.cut();
try {
let execute = printer.execute()
console.error("Print done!");
} catch (error) {
console.log("Print failed:", error);
