[Python] how to save opened page as pdf in Selenium (Python)

Have tried all the solutions I could find on the Internet to be able to print a page that is open in Selenium in Python. However, while the print pop-up shows up, after a second or two it goes away, with no PDF saved.

Here is the code being tried. Based on the code here - https://stackoverflow.com/a/43752129/3973491

Coding on a Mac with Mojave 10.14.5.

from selenium import webdriver
from selenium.webdriver.support.select import Select
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.chrome.options import Options
from selenium.common.exceptions import WebDriverException
import time
import json

options = Options()
appState = {
"recentDestinations": [
{
"id": "Save as PDF",
"origin": "local"
}
],
"selectedDestinationId": "Save as PDF",
"version": 2
}

profile = {'printing.print_preview_sticky_settings.appState': json.dumps(appState)}
# profile = {'printing.print_preview_sticky_settings.appState':json.dumps(appState),'savefile.default_directory':downloadPath}
options.add_experimental_option('prefs', profile)
options.add_argument('--kiosk-printing')
CHROMEDRIVER_PATH = '/usr/local/bin/chromedriver'

driver = webdriver.Chrome(options=options, executable_path=CHROMEDRIVER_PATH)
driver.implicitly_wait(5)
driver.get(url)
driver.execute_script('window.print();')


$chromedriver --v
ChromeDriver 75.0.3770.90 (a6dcaf7e3ec6f70a194cc25e8149475c6590e025-refs/branch-heads/3770@{#1003})


Any hints or solutions as to what can be done to print the open html page to a PDF. Have spent hours trying to make this work. Thank you!


Update on 2019-07-11:

My question has been identified as a duplicate, but a) the other question seems to be using javascript code, and b) the answer does not solve the problem being raised in this question - it may be to do with more recent software versions. Chrome version being used is Version 75.0.3770.100 (Official Build) (64-bit), and chromedriver is ChromeDriver 75.0.3770.90. On Mac OS Mojave. Script is running on Python 3.7.3.

Changed the code to

from selenium import webdriver
import json

chrome_options = webdriver.ChromeOptions()
settings = {
"appState": {
"recentDestinations": [{
"id": "Save as PDF",
"origin": "local",
"account": "",
}],
"selectedDestinationId": "Save as PDF",
"version": 2
}
}
prefs = {'printing.print_preview_sticky_settings': json.dumps(settings)}
chrome_options.add_experimental_option('prefs', prefs)
chrome_options.add_argument('--kiosk-printing')
CHROMEDRIVER_PATH = '/usr/local/bin/chromedriver'
driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=CHROMEDRIVER_PATH)
driver.get("https://google.com")
driver.execute_script('window.print();')
driver.quit()


And now, nothing happens. Chrome launches, loads url, print dialog appears but then nothing seems to happen - nothing in the default printer queue, and no pdf either - I even searched for the PDF files by looking up "Recent Files" on Mac.
