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:
js
window.addEventListener("afterprint", resumeFunction);
Syntax
js
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:
js
browser.browserAction.onClicked.addListener(() => {
browser.tabs.printPreview().then(() => {
console.log("Entered print preview");
});
});
