Question

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

Answer 1

The solution is not very good, but you can take a screenshot and convert to pdf by Pillow...

from selenium import webdriver
from io import BytesIO
from PIL import Image

driver = webdriver.Chrome(executable_path='path to your driver')
driver.get('your url here')
img = Image.open(BytesIO(driver.find_element_by_tag_name('body').screenshot_as_png))
img.save('filename.pdf', "PDF", quality=100)

You can use the following code to print PDFs in A5 size with background css enabled:

import os
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import json
import time

chrome_options = webdriver.ChromeOptions()

settings = {
    "recentDestinations": [{
        "id": "Save as PDF",
        "origin": "local",
        "account": ""
    }],
    "selectedDestinationId": "Save as PDF",
    "version": 2,
    "isHeaderFooterEnabled": False,
    "mediaSize": {
        "height_microns": 210000,
        "name": "ISO_A5",
        "width_microns": 148000,
        "custom_display_name": "A5"
    },
    "customMargins": {},
    "marginsType": 2,
    "scaling": 175,
    "scalingType": 3,
    "scalingTypePdf": 3,
    "isCssBackgroundEnabled": True
}

mobile_emulation = { "deviceName": "Nexus 5" }
chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
chrome_options.add_argument('--enable-print-browser')
#chrome_options.add_argument('--headless')

prefs = {
    'printing.print_preview_sticky_settings.appState': json.dumps(settings),
    'savefile.default_directory': '<path>'
}
chrome_options.add_argument('--kiosk-printing')
chrome_options.add_experimental_option('prefs', prefs)

for dirpath, dirnames, filenames in os.walk('<source path>'):
    for fileName in filenames:
        print(fileName)
        driver = webdriver.Chrome("./chromedriver", options=chrome_options)
        driver.get(f'file://{os.path.join(dirpath, fileName)}')
        time.sleep(7)
        driver.execute_script('window.print();')
        driver.close()

The answer here, worked when I did not have any other printer setup in my OS. But when I had another default printer, this did not work.

I don't understand how, but making small change this way seems to work.

from selenium import webdriver
import json

chrome_options = webdriver.ChromeOptions()
settings = {
       "recentDestinations": [{
            "id": "Save as PDF",
            "origin": "local",
            "account": "",
        }],
        "selectedDestinationId": "Save as PDF",
        "version": 2
    }
prefs = {'printing.print_preview_sticky_settings.appState': 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()

Here is the solution I use with Windows :

• First download the ChromeDriver here : http://chromedriver.chromium.org/downloads and install Selenium

• Then run this code (based on the accepted answer, slightly modified to work on Windows):

  import json
  from selenium import webdriver
  chrome_options = webdriver.ChromeOptions()
  settings = {"recentDestinations": [{"id": "Save as PDF", "origin": "local", "account": ""}], "selectedDestinationId": "Save as PDF", "version": 2}
  prefs = {'printing.print_preview_sticky_settings.appState': json.dumps(settings)}
  chrome_options.add_experimental_option('prefs', prefs)
  chrome_options.add_argument('--kiosk-printing')
  browser = webdriver.Chrome(r"chromedriver.exe", options=chrome_options)
  browser.get("https://google.com/")
  browser.execute_script('window.print();')
  browser.close()
