how to print a PDF document using selenium python?-CodePudding

I need to print a PDF file after having "downloaded" it using a selenium script. The issue is that it opens in a pop up window, however selenium should be able to handle that. This is the source code of the toolbar i want to interact with:

<div id="toolbar"><div id="start"><cr-icon-button id="sidenavToggle" iron-icon="cr20:menu" title="Menu" aria-label="Menu" aria-expanded="true" aria-disabled="false" role="button" tabindex="0"></cr-icon-button><span id="title">rdlComprobanteJubilados</span></div><div id="center"><viewer-page-selector style="--page-length-digits:1;"></viewer-page-selector><span ></span><span id="zoom-controls"><cr-icon-button iron-icon="pdf:remove" title="Zoom out" aria-label="Zoom out" aria-disabled="false" role="button" tabindex="0"></cr-icon-button><input type="text" value="100%" aria-label="Zoom level"><cr-icon-button iron-icon="pdf:add" title="Zoom in" aria-label="Zoom in" aria-disabled="false" role="button" tabindex="0"></cr-icon-button></span><span ></span><cr-icon-button id="fit" aria-label="Fit to page" title="Fit to page" aria-disabled="false" role="button" tabindex="0" iron-icon="pdf:fit-to-height"></cr-icon-button><cr-icon-button iron-icon="pdf:rotate-left" dir="ltr" aria-label="Rotate counterclockwise" title="Rotate counterclockwise" aria-disabled="false" role="button" tabindex="0"></cr-icon-button></div><div id="end"><viewer-download-controls id="downloads"></viewer-download-controls><cr-icon-button id="print" iron-icon="cr:print" title="Print" aria-label="Print" aria-disabled="false" role="button" tabindex="0"></cr-icon-button><cr-icon-button id="more" iron-icon="cr:more-vert" title="More actions" aria-label="More actions" aria-disabled="false" role="button" tabindex="0"></cr-icon-button></div></div>

although the full source code is here.

I want to interact with this element:

<cr-icon-button id="print" iron-icon="cr:print" title="Print" aria-label="Print" aria-disabled="false" role="button" tabindex="0"></cr-icon-button>

my current approach is this:

for handle in driver.window_handles:
    if driver.current_window_handle!=handle:
        driver.switch_to.window(handle)
        print("changed")
pbutton=filebutton=driver.find_element(By.ID,"print")
pbutton.click()
Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, '//*[@id="print"]')))).select_by_index(2)
print("pass")

which yields this error:

NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"[id="print"]"}

i´m running Python 3.9.7 and Selenium 4.3.0 and i work with Jupyter Notebooks installed with Anaconda and the browser used is Google Chrome Versión 104.0.5112.81 (Build oficial) (64 bits) I need the solution to work as a standalone script and preferably OS agnostic although if that´s not possible it would be enough to have it run in Linux Mint

CodePudding user response：

To click on the desired element you can use either of the following locator strategies:

Using CSS_SELECTOR:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "cr-icon-button#print[title='Print'][aria-label='Print']"))).click()

Using XPATH:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//cr-icon-button[@id='print' and @title='Print'][@aria-label='Print']"))).click()

Note: You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

I finally found a way to solve it WITHOUT interacting with the PDF viewer. i used the option module:

from selenium.webdriver.chrome.options import Options
DRIVER_PATH = r"C:\Users\HP\Downloads\chromedriver_win32\chromedriver.exe"
chrome_options = Options()
chrome_options.add_experimental_option('prefs', {
"download.default_directory": r"C:\Users\HP\Desktop\test downloads", #Change default directory for downloads
"download.prompt_for_download": False, #To auto download the file
"download.directory_upgrade": True,
"plugins.always_open_pdf_externally": True #It will not show PDF directly in chrome
})

driver = webdriver.Chrome(executable_path=DRIVER_PATH,options = chrome_options)
driver.implicitly_wait(60)
