Python script to add JS to pdf so the pdf will print immediately when opened

python-printJS-in-pdf.py

# IE users need: https://get.adobe.com/reader/

from PyPDF2 import PdfFileWriter, PdfFileReader

output = PdfFileWriter()
ipdf = PdfFileReader(open('old.pdf', 'rb'))

for i in xrange(ipdf.getNumPages()):
	page = ipdf.getPage(i)
	output.addPage(page)

with open('new.pdf', 'wb') as f:
	output.addJS("this.print({bUI:true,bSilent:false,bShrinkToFit:true});")
	output.write(f)

Updated version for python 3.x

from PyPDF2 import PdfWriter, PdfReader

output = PdfWriter()
ipdf = PdfReader(open('old.pdf', 'rb'))

for i in range(len(ipdf.pages)):
    page = ipdf.pages[i]
    output.add_page(page)

with open('new.pdf', 'wb') as f:
    output.add_js("this.print({bUI:true,bSilent:false,bShrinkToFit:true});")
    output.write(f)

Hi @RaymonDev,
This not working for Chrome, the PDF is opened without any action
what is the expected output for this.

I honestly have no idea. I just translated the code to 3.x, working on it though!!

Ok, Did you try it in Chrome ?

Yes, still not working
