Examples

To print a file to the default printer, use the following code:

import { print } from "qs-pdf-to-printer";

print("assets/sample.pdf").then(console.log);

To print to a specific printer:

import { print } from "qs-pdf-to-printer";

const options = {
  printer: "Zebra",
};

print("assets/pdf-sample.pdf", options).then(console.log);

import { print } from "qs-pdf-to-printer";

const options = {
  printer: "Zebra",
  pages: "1-3,5",
  scale: "fit",
};

print("assets/pdf-sample.pdf", options).then(console.log);

getPrinters().then(console.log);

.getDefaultPrinter() => Promise<Printer | null>

A function to get the default printer information.
