tabs.printPreview()

Opens print preview for the active tab.

This is an asynchronous function that returns a Promise. An extension can detect when print preview has been closed by listening to the afterprint event:

window.addEventListener("afterprint", resumeFunction);

Syntax

let openingPreview = browser.tabs.printPreview()

Parameters

None.

Return value

A Promise that will be fulfilled with no arguments when the preview page has opened.

Examples

In this example a background script listens for a click on a browser action, then opens print preview for the currently active tab:

browser.browserAction.onClicked.addListener(() => {
  browser.tabs.printPreview().then(() => {
    console.log("Entered print preview");
  });
});
