web_disable_print.js

odoo.define("web_disable_print", function(require) {
    "use strict";

    var ListView = require('web.ListView');

    ListView.include({
        init: function (viewInfo, params) {
            this._super.apply(this, arguments);
            var print = this.arch.attrs.print ? JSON.parse(this.arch.attrs.print) : true;
            if (print === false) {
                delete this.controllerParams.toolbarActions['print'];
            }
        },
    });
});
