2 question about invoice

[Sassolino]

Hello,

I do not know if the section is correct, I hope so.

1) I am trying to change the layout of the invoices, I did a search and found some information about the file to edit. I downloaded the FPDF manual, which I find easy, but the file PDF.PHP is a real mess!

There is a guide, a simple path or indications of which parts of the file PDF.PHP act of which part of the bill? And if I wanted to also change the shipping document and credit note?

2) At year end Prestashop automatically resets the counters and leaves all the existing documents available, or there is some maneuvering to do manually?

 

thanks

I use prestashop 1.4.4.1
