Steps to reproduce the problem:
Using Headless and Printing to PDF, there is currently no way to adjust the pageNumber generated by Chromium.

What is the expected behavior?
An option to set an integer offset that would be applied to all pageNumbers, default would be 0.

What went wrong?
No current way to specify an offset on page-numbers. They are always iterated from 0.

Did this work before? No 

Does this work in other browsers? Yes
