Two Blog Layouts, Same Theme

YES! You need 2 custom templates. One for standard view for your visitors and second for your review printout. But you need to create also for that second printout page header and footer manualy and also some functionality. You can’t use the same head and footer from other pages. Or you can but you then need to overwrite funcionality what you don’t need there or disable.

You need to be there just carefull and be clear what you want there. Is not that complicated but can made a mess on that “special” page. Loop of posts can be the same just with new HTML, JS and CSS in printout page.
