Answer 1

When Odoo launch the download action of a report it will check if close_on_report_download action attribute is set to true, if so it will return action of type ir.actions.act_window_close which will close the wizard.
#api.multi
def print_pdf(self):
action = self.env.ref('customer_products.pdf_products').report_action(self)
action.update({'close_on_report_download': True})
return action
Edit:
You can implement the same logic, override QWEBActionManager and check if the option is passed through the action definition and if yes close the window.
var ActionManager = require('web.ActionManager');
var session = require('web.session');
ActionManager.include({
ir_actions_report: function (action, options) {
var self = this;
return $.when(this._super.apply(this, arguments), session.is_bound).then(function() {
if (action && action.report_type === 'qweb-pdf' && action.close_on_report_download) {
return self.do_action({ type: 'ir.actions.act_window_close' });
}
});
},
});
