How to config interface using tcp, local or selecting printer?
Hi @Klemen1337 thanks for this module.
I have a question on how to ultimately send the commands to the printer.
From the code I see that you accumulate a Buffer with all the commands but how do you connect to the printer and send the buffer from the browser?
I see the Tested printers section in the README. Can you provide an example on what you're using to send the buffer commands to the printer?
I would like to use this lib on my typescript project. Sadly, types are not exported.
And when i try to import from:
import ThermalPrinter, { PrinterTypes } from 'browser-thermal-printer/src/core';
My typescript fails because my project has stricter rules.
Error: node_modules/browser-thermal-printer/src/interfaces/epson/epson.ts:251:30 - error TS2769: No overload matches this call.
The last overload gave the following error.
Type 'string | undefined' is not assignable to type 'string'.
Type 'undefined' is not assignable to type 'string'.
Type 'number' is not assignable to type 'string'.
251 this.append(Buffer.from([type, data.length]));
Is there away to export the.d.ts files two please.
Hello!
I was trying to implement this library in reactjs and I cannot get It working, do you have any example using reactjs?
import ThermalPrinter, { PrinterTypes, TableAlign } from "../src/core"
async function printTest() {
const printer = new ThermalPrinter();
printer.print("Hello World"); // Append text
printer.println("Hello World"); // Append text with new line
}
module.exports = {
printTest: printTest
};
I know that doesn't work because '../src/core' but if I try with
const ThermalPrinter = require('browser-thermal-printer');
It doesn't works. I got this error: TypeError: ThermalPrinter is not a constructor
Any help?
