[🐛 Bug]: print_page method does not adhere to page_height and page_width declared in PrintOptions

[MrChadMWood]

What happened?

Hello,

Method: driver.print_page
Issue: does not ahere to selenium.webdriver.common.print_page_options.PrintOptions declared page_height and page_width

Recently attempted to customize the resulting PDF size after using driver.print_page().
Given 72 points per inch, the resulting PDF does not appear to adhere to the preconfigured customization.

I set page height and page width to 10". The resulting yield was a 284x284pt PDF, which by my understand equates to 3.94".
The expected output was a file of size 720x720pt, or 10"x10".

How can we reproduce the issue?

Python 3.11.2
selenium==4.9.1
pdfminer==20191125

from selenium import webdriver
import base64
from pdfminer.pdfparser import PDFParser
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfpage import PDFPage


driver = webdriver.Firefox(options=options)
driver.get('https://www.google.com')

print_options = PrintOptions()
print_options.page_height = 10
print_options.page_width = 10

pdf = driver.print_page(print_options=print_options)
driver.close()

# save the output to a file.
with open('example.pdf', 'wb') as file:
    file.write(base64.b64decode(pdf))
    
# verify the page size of the PDF file created
parser = PDFParser(open('example.pdf', 'rb'))
doc = PDFDocument(parser)
pageSizesList = []
for page in PDFPage.create_pages(doc):
    print(page.mediabox)

Current workaround: multiply desired dimension by value of 2.5352112676056335

from selenium import webdriver
import base64
from pdfminer.pdfparser import PDFParser
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfpage import PDFPage

# Function to find page size
S = lambda X: driver.execute_script('return document.body.parentNode.scroll'+X)

# Ratio to achieve desired size (for me atleast)
RATIO_MULTIPLIER = 2.5352112676056335

driver = webdriver.Firefox(options=options)
driver.get('https://www.google.com')

print_options = PrintOptions()
print_options.page_height = 10*RATIO_MULTIPLIER
print_options.page_width = 10*RATIO_MULTIPLIER
print_options.shrink_to_fit = True

pdf = driver.print_page(print_options=print_options)
driver.close()

# save the output to a file.
with open('example.pdf', 'wb') as file:
    file.write(base64.b64decode(pdf))
    
# verify the page size of the PDF file created
parser = PDFParser(open('example.pdf', 'rb'))
doc = PDFDocument(parser)
pageSizesList = []
for page in PDFPage.create_pages(doc):
    print(page.mediabox)

OUTPUT

[0, 0, 719, 719]

Expected result was 720x720. Close.
