在 PhantomJS 中打印页面

Question

Is there any way to print a page in PhantomJS . I want to pass my page to PDF Printer ( PDFCreator ) in order to get a good-looking PDF page ( See my question here )

I'm using the following code, but it doesn't work

var page = require('webpage').create(),
address, output, size;

var input = phantom.args[0];
page.open(input, function (status) {
    page.evaluate(function () {
        window.print();
    });
    phantom.exit();
});

Answer 1

Maybe this helps: You need to set a larget timeout in rasterize.js in order to allow for the entire document to render before you do page.render(output)

Also, the script you provided is very different from what rasterize.js does and it won't work.

Looks like PhantomJS has examples included on its website . One of them, rasterize.js , says it shows how to output the HTML as a PDF. I haven't tried it, but perhaps that could lead to a solution.

I found this gist: https://gist.github.com/boriscy/a0ac26c54f30296949df which does what looks like a crucial thing:

page.onLoadFinished = function() {
  page.render(pdf);
  phantom.exit();
}

The other examples I have seen put in a big wait and just hope by the time the wait is over the document is done. To me that doesn't seem great as bigger documents will fail, and smaller documents will be slower than needed.
