Does anybody know how to launch the print dialog from chrome by selenium+python

问题

I have a question about how to launch the print dialog from chrome browser. I know the shortcut key to open this is ctrl+p, but I don't know how to describe it in selenium. Does anyone know this? Thanks a lot!

I tried the following code, but it doesn't work on my Chrome browser.

    actions = ActionChains(driver)
    actions.move_to_element(driver.find_element_by_tag_name('body'))
    actions.key_down(Keys.CONTROL).send_keys('T').key_up(Keys.CONTROL).perform()

Not quite what you are asking about, but this is what worked for me in Firefox.

Send CTRL+P (or COMMAND+P on mac) to the body element using ActionChains:

from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://google.com")

actions = ActionChains(driver)
actions.move_to_element(driver.find_element_by_tag_name('body'))
actions.key_down(Keys.CONTROL).send_keys('p').key_up(Keys.CONTROL)
actions.perform()

Basically you need to trigger the JavaScript function that triggers the print pop-up. That function is window.print().

So what you need is to trigger that function after arriving at the page you want to print. So say you want to print the front page of stackoverflow.com

driver.get("https://stackoverflow.com")
# now you're at the page you want to print. Trigger print function
driver.execute_path("window.print()")

Now it should prompt you to the print pop-up. The reason you need to trigger the JavaScript function is because JavaScript is the browser's language.
