How to close print windows dialog in Protractor Test

Question

I am doing end-to-end testing with protractor. In a certain test, I need to test like print button is creating pdf or not. So When Test clicks the button, It opens the print window dialog like below.

And now this test is not able to be finished. because of this print window. My question is how to close this print dialog in protractor? Because of it, rest of test become pending. Please help. Thanks in advance.

EDIT

I have tried like this..

var printButton=element(by.css('[class="print"]'));
        /* This print button should be present first*/
        expect(printButton.isPresent()).toBe(true);

        browser.actions().mouseMove(printButton).perform();
        printButton.click().then(function () {
             // fill in the form here
             browser.sleep(2000);
            // For Pressing Escape key
            browser.actions().sendKeys(protractor.Key.ESC).perform();

        });

I thought If i got successful to press escape key, then It will resolve the issue.But No Success.

NEXT EDIT-- I have tried new Windows change like below

printButton.click().then(function () {
             // fill in the form here

            browser.sleep(4000);
            browser.getAllWindowHandles().then(function(handles){
                browser.switchTo().window(handles[1]).then(function(){
                    //do your stuff on the pop up window

                    browser.driver.close();
                    browser.switchTo().window(handles[0]);
                });
            });

        });

but it shows an error in console and actually It does not open any windows. and hungs up on print dialog as previous.

 Failed: unknown error: failed to close window in 20 seconds

EDIT 3

I am having this problem in angular js not in java.

EDIT 4 My Last Attempt

printButton.click().then(function () {
             // fill in the form here
            return browser.getAllWindowHandles().then(function (handles) {
                var newWindowHandle = handles[1]; // this is your new window
                return browser.switchTo().window(newWindowHandle).then(function () {
                    return browser.sleep(5000).then(function () {
                        return browser.actions().sendKeys(protractor.Key.ESCAPE).perform().then(function () {
                            return browser.switchTo().window(handles[0])
                        });
                    });
                });
            });

But It does not open a new tab for print Dialog..open print Dialog in same tab.

Answer 1

You need to send the escape to the right window. Also wait for the window to be open before you send it. You probably also need to switch back to handles[0].

return browser.getAllWindowHandles().then(function (handles) {
    var newWindowHandle = handles[1]; // this is your new window
    return browser.switchTo().window(newWindowHandle).then(function () {
        return browser.sleep(5000).then(function () {
            return browser.actions().sendKeys(protractor.Key.ESCAPE).perform().then(function () {
                return browser.switchTo().window(handles[0])
            });
        });
    });
});

Set the capabilities as below; this will disable the print preview pop up from chrome browser

capabilities: { 'browserName': 'chrome', chromeOptions: { args: ['--disable-print-preview','start-maximized'] }

},
