Trying to create a cross-browser compatible HTML brochure

So, I have a PDF brochure in which we are trying to create a printable version of HTML. I encounter several obstacles, including:

• 100% scaling compared to Shrink to match (default values ​​in FF / IE are different)
• Printing only one page and lack of space after (or even just “page break: always” to work)
• I have a liquid layout that I am trying to use only width: auto on the main shell, but that means there are no width restrictions on the front end of the HTML page. I do not want to use a minimum width or anything else. I hope that since this page is strictly for printing, I will not need to add a sheet of print styles (just typing this, it seems to me that I really need ...)
• Should I use a fixed layout on an HTML page and a fluid layout on a print page?

Perhaps I thought about it ...

Thanks so much for any help.
