   • scale (string, optional): Supported names are noscale, shrink, and fit.
   • monochrome (boolean, optional): Prints the document in black and white. The default value is false.
   • side (string, optional): Supported names are duplex, duplexshort, duplexlong, and simplex.

Examples

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

import { print } from "nyexprinter";

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

To print to a specific printer:

import { print } from "nyexprinter";

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

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

Here is an example with a few print settings. It will print pages 1, 3, and 5, and scale them so that they fit into the printable area of the paper.

import { print } from "nyexprinter";

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

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

.getPrinters() => Promise<Printer[]>

A function to get a list of available printers.

Returns

Promise<Printer[]>: a Promise that resolves with a list of available printers.

Examples

import { getPrinters } from "nyexprinter";

getPrinters().then(console.log);

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

A function to get the default printer information.

Returns

Promise<Printer | null>: a Promise that resolves with the default printer information, or null if there is no default printer.

Examples

import { getDefaultPrinter } from "nyexprinter";

getDefaultPrinter().then(console.log);
