We have a process where we collect a lot of information that are compiled in a couple multi-page output documents needing to have a particular layout. Namely, the company header, footer, official formatting, etc.
Currently TCPDF and HTML2PDF do not the job. The result does not match what is in the designer, most CSS is dropped and has many other isssues. In other projects we use wkhtmltopdf which prints documents as intended.
So, how can I implement my own wkhtmltopdf based generator and ideally submit my contribution upstream?
