PDF generate problem

Can anyone shed some light on exactly how they upgraded to the latest version of wkhtmltopdf ??

I thought the version in use had special changes specific to frappe framework.

I would like to upgrade my version as well but I am unsure exactly how. I have read so many horror stories about trying to do it from the repo that you end up with versions missing qr patches or missing frappe patches.

Any help or pointers to a success story would be greatly appreciated.
