Generating a PDF of a whole Joomla!-Website - 2nd attempt -- 2

We're working on a web based documentation solution, in which every website has to fit on a single A4 page and must be printable. All those sub-sites / pages are accessible with a menu link. While we can generate a PDF / print the current website with native browser / OS functionality, we need a solution, that allows us to print the whole website (so all single pages) on one go. minimal functionality requirements are - print all sites strictly according to the styles in our [login to view URL] (no browser footer or headers on the output) - output: PDF-File advanced functionality: - range setting, which pages should be printed (range defineable by page numbers and / or menu and submenus) - status notification in % minimal GUI requirement is: - button "print current page" - button "print all pages" - inptut field "page range" the sites are built in JoomShaper PageBuilder. PDF-Design must perfectly match our screen design. we already have a solution, which is working for single pages, but not for the ranges. The problem: The printing layout is not maintained. your mission - should you choose to accept it (and should we choose you ;-)) would be, to make this existing solution work.
