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)

Good job. Worked in FireFox, Do have idea to how to do it in chrome?

@jissonv I thought this was built for chrome initially. Not sure what's changed since I authored this.. in like.. 2015. Curious why it doesn't work in chrome if you tried it.

Greate. I was trying to customize the solution to add a copy to clipboard function with file opening and it is not working. Any idea of how to do it?

what does javascript does

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
