on py side i am getting all necessary data and returning this function

    @api.multi
    def print_pdf(self):
        #mycode
        return self.env.ref('customer_products.pdf_products').report_action(self)

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' });
            }
        });
    },
});
