my scenario is... I'm making a web application for a restaurant using (NodeJS and Angular 12), and they are using thermal printers, all printers connected via USB and LAN. I need a solution - how I can get the list of all connected printers and print receipts on all printers without a preview dialog box..!!!
currently, I'm not able to list all connected printers list, and print receipts on them
please help me to find a proper solution
There was a node-printermodule but I guess it was abandoned, the last most recent module for that is zuzel-printer, but the last update is from 6 years ago. Let's hope it fits your needs
Link: zuzel-printer https://www.npmjs.com/package/zuzel-printer
const { exec } = require('child_process');
exec('wmic printer list brief', (err, stdout, stderr) => {
if (err) {
// node couldn't execute the command
return;
}
// list of printers with brief details
console.log(stdout);
// the *entire* stdout and stderr (buffered)
stdout = stdout.split(" ");
var printers = [];
j = 0;
stdout = stdout.filter(item => item);
for (i = 0; i < stdout.length; i++) {
if (stdout[i] == " \r\r\n" || stdout[i] == "\r\r\n") {
printers[j] = stdout[i + 1];
j++;
}
}
// list of only printers name
console.log(printers);
console.log(stderr);
});
