我试图从HP打印机中清除打印日志。页面内容无法加载。以下错误是一个线索，但我不确定我是否知道如何规避它。
<noscript> <div id="pgm-no-js-text"> <p>JavaScript is
required to access this website.</p>
<p>Please enable JavaScript or use a browser that supports
JavaScript.</p> </div> </noscript>
以下是我使用
的代码var url =''; // printer web interface IP, tried http:// and https://
var page = require('webpage').create();
console.log("klik 0");
page.settings.userAgent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36';
//page.settings.javascriptEnabled = true;
//page.viewportSize = { width: 1920, height: 1080 };
page.onLoadFinished = function() {
console.log("### finished loading page");
};
page.open(url, function(status) {
setTimeout(function() {
console.log("Status: " + status);
if (status === "success") {
console.log("klik1 OK");
console.log(page.content);
phantom.exit(1);
} else {
console.log("eeeek, no go");
phantom.exit();
}
}, 3000);
});
是否可以在页面上实现额外的.js脚本（大小为600 kb）
<script src="./HP Officejet Pro X476dw MFP_files/Unified.js" type="text/javascript"></script>
以某种方式阻止我手动加载页面？如果我通过page.render制作屏幕截图，但它只加载部分背景而不是其他内容。关于我如何自己调试这个问题的任何提示都将非常感激。
我执行phantomjs --debug=true script.js时的详细调试输出。在Ubuntu 16.04上，PhantomJS的版本是2.1.1。
