In the the Layout palette, use the System break tool (yellow highlighter) to move the following measure to a new line (a new "system"). Use the Page break tool (red-orange highlighter) to move the following measure to a new page.
To get four bars on each page, put a System break in every bar. Then put the Page break in every fourth bar.
(I suspect this isn't what you actually want/need, but that's how to do what you asked for.)
