Dear,

the problem: when printing survey results, it appear to be in one page and not as multipage.

odoo 14, entreprise.

I found a reason: the style for html, body height must be on "unset", instead of 100%

the problem does not appear when the module "planning" is installed, because style of planning contain html, body{height: unset;}

but in you uninstall this module, you will see the problem when printing mutipage survey result for example. I tried it with runbot.odoo.com

my solution is adding this in my theme:

@media print{

 html, body{height: unset;

}
