Print with Google Chrome Extension

Question

I am trying to choose the printer in the default chrome dialog via a Chrome Extension, but have not be to get PrinterProvider events to trigger at all in my extension. Is PrinterProvider the correct way to go about this? If so, any examples would be helpful. Is it possible to select which printer name shows up in the printer dropdown?

For example, I have the following in my background.js and the event is never triggered:

chrome.printerProvider.onPrintRequested.addListener(async (chromePrintJob, printRequestCallback) => {
  console.log("Print requested");
  await chromePrintJob.document.text();
  console.log("resolve");
  printRequestCallback("OK");

});

This isn't possible. Chrome does not give extensions that kind of control over its UI. Moreover, default printer selection is typically an OS-level setting.

No, that interface allows an extension to act as a printer, not to modify existing printers. In other words, you can use PrinterProvider in your extension to add new printers the user can select in the print dialog window and handle print jobs sent to your custom printer.
