2. options (Object, optional):
   • printer ( string, optional): Sends the file to the specified printer.
   • pages (string, optional): Specifies which pages to print in the PDF document.
   • subset (string, optional): Prints odd pages only when the value is odd, and even pages only when it is even.
   • orientation (string, optional): Provides 90-degree rotation of contents (NOT the rotation of paper which must be pre-set by the choice of printer defaults).
   • 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.
   • bin (string, optional): Select tray to print to. Number or name.
   • paperSize (string, optional): Specifies the paper size. A2, A3, A4, A5, A6, letter, legal, tabloid, statement, or a name selectable from your printer settings.
   • silent (boolean, optional): Silences error messages.
   • printDialog (boolean, optional): Displays the print dialog for all the files indicated on this command line.
   • copies(number, optional): Specifies how many copies will be printed.

Returns

Promise<void>: A Promise that resolves with undefined.

Examples

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

const { print } = require("nodejs-printer");

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

To print to a specific printer:

const { print } = require("nodejs-printer");

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.

const { print } = require("nodejs-printer");

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

const { getPrinters } = require("nodejs-printer");

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

const { getDefaultPrinter } = require("nodejs-printer");

getDefaultPrinter().then(console.log);
