How to convert webpage into PDF by using Python

I was finding solution to print webpage into local file PDF, using Python. one of the good solution is to use Qt, found here,

It didn't work at the beginning as I had problem with the installation of PyQt4 because it gave error messages such as 'ImportError: No module named PyQt4.QtCore', and 'ImportError: No module named PyQt4.QtCore'.

It was because PyQt4's not installed properly.
I used to have the libraries located at C:\Python27\Lib however it's not for PyQt4.

In fact, it simply needs to download from (mind the correct Python version you are using), and install it to C:\Python27 (my case). That's it.

Now the scripts runs fine so I want to share it. for more options in using Qprinter, please refer to

thanks to below posts, and I am able to add on the webpage link address to be printed and present time on the PDF generated, no matter how many pages it has.

Add text to Existing PDF using Python

To share the script as below:

import time
from pyPdf import PdfFileWriter, PdfFileReader
import StringIO
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter
from xhtml2pdf import pisa
import sys 
from PyQt4.QtCore import *
from PyQt4.QtGui import * 
from PyQt4.QtWebKit import * 

url = ''
tem_pdf = "c:\\tem_pdf.pdf"
final_file = "c:\\younameit.pdf"

app = QApplication(sys.argv)
web = QWebView()
#Read the URL given
printer = QPrinter()
#setting format
#export file as c:\tem_pdf.pdf

def convertIt():

QObject.connect(web, SIGNAL("loadFinished(bool)"), convertIt)


# Below is to add on the weblink as text and present date&time on PDF generated

outputPDF = PdfFileWriter()
packet = StringIO.StringIO()
# create a new PDF with Reportlab
can = canvas.Canvas(packet, pagesize=letter)
can.setFont("Helvetica", 9)
# Writting the new line
oknow = time.strftime("%a, %d %b %Y %H:%M")
can.drawString(5, 2, url)
can.drawString(605, 2, oknow)

#move to the beginning of the StringIO buffer
new_pdf = PdfFileReader(packet)
# read your existing PDF
existing_pdf = PdfFileReader(file(tem_pdf, "rb"))
pages = existing_pdf.getNumPages()
output = PdfFileWriter()
# add the "watermark" (which is the new pdf) on the existing page
for x in range(0,pages):
    page = existing_pdf.getPage(x)
# finally, write "output" to a real file
outputStream = file(final_file, "wb")

print final_file, 'is ready.'
