Answer a question

I'm trying to save a website as PDF through printing dialog. My code allows me to save as pdf, but asks me to input a filename, which I don't know how to pass a filename to the pop up box. Attached is my code:

import time
from selenium import webdriver
import os

class printing_browser(object):
    def __init__(self):
        self.profile = webdriver.FirefoxProfile()
        self.profile.set_preference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", False)
        self.profile.set_preference("pdfjs.disabled", True)
        self.profile.set_preference("print.always_print_silent", True)
        self.profile.set_preference("print.show_print_progress", False)
        self.profile.set_preference("browser.download.show_plugins_in_list",False)
        foxdriver = r'C:\Users\AShen\Documents\Workspace\geckodriver.exe'
        self.driver = webdriver.Firefox(executable_path=foxdriver,firefox_profile = self.profile)
        time.sleep(5)

    def get_page_and_print(self, page):
        self.driver.get(page)
        time.sleep(5)
        self.driver.execute_script("window.print();")

if __name__ == "__main__":
    browser_that_prints = printing_browser()
    browser_that_prints.get_page_and_print('http://www.google.com/')

Oh, it is very easy if you know about pyautogui. This is an amazing module that allows you to automate your curser. So essentially, you need to figure out the place where the popup appears and use pyautogui to click it for you. All you need to add is:

time.sleep(3)

i=random.randint(0,1000)
file_name=('name_pdf '+str(i))
print (file_name)


pyautogui.typewrite(file_name)
pyautogui.click(512,449)

Entire code structure will look like this:

import time
import pyautogui
from selenium import webdriver
import os

class printing_browser(object):
    def __init__(self):
        self.profile = webdriver.FirefoxProfile()
        self.profile.set_preference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", False)
        self.profile.set_preference("pdfjs.disabled", True)
        self.profile.set_preference("print.always_print_silent", True)
        self.profile.set_preference("print.show_print_progress", False)
        self.profile.set_preference("browser.download.show_plugins_in_list",False)
        foxdriver = r'C:\Users\Pranjal Pathak\Desktop\Titanic Kaggle\geckodriver.exe'
        self.driver = webdriver.Firefox(executable_path=foxdriver,firefox_profile = self.profile)
        time.sleep(5)

    def get_page_and_print(self, page):
        self.driver.get(page)
        time.sleep(5)
        self.driver.execute_script("window.print();")

if __name__ == "__main__":
    browser_that_prints = printing_browser()
    browser_that_prints.get_page_and_print('http://www.python.org/')

time.sleep(3)

i=random.randint(0,1000)
file_name=('name_pdf '+str(i))
print (file_name)


pyautogui.typewrite(file_name)
pyautogui.click(512,449)

Note: 1. I have selected the name of the file as name+any random integer between 1 to 1000 to change name every time you save the file. This way it will save every time you run the code as the names will be different every time.

2. If this types the name but does not save the file, you might want to change the coordinates of your curser. Let me know if that happens.
