print a remote pdf

Can you print a remote PDF? Existing Features Printing a remote file will report a cross-domain error, but in general, the file server may not be in the same domain as the application server

@weihongyu12 , we can't print a remote pdf because of the cross-domain protection and the same-origin policy.

I'll check if we there is way to work around it. Maybe we can implement a solution in the library.

I'm also looking for a way to print a remote pdf.
Using this library we have cross-origin error frame.

Can you imagine a way to do it?

Try PDF.js?

You could create a server endpoint that acts a proxy.

i.e. http://myapp.com/cool_pdf.pdf could route to a server-side function that grabs the remote PDF and renders it.

I haven't found a solid solution to work around the some-origin policy and allow the lib to print remove pdf files. As it uses iframe to load the pdf before printing it, the error will always occurs.

I recommend using the solution above suggested by Steve.

I implemented a better pdf pre-loading logic which I just realized it solved the issue when printing remote pdf files.
The file will be fetched via a http request and saved into a local blob url. When sending this url to the iframe, the browser won't block it since it is not longer a remote file.

Here is an example:

For now, it will only do this when preloading, which means, we have to pass the showModal parameter as true or use a hook function onLoadingStart.
I'm not sure that is worth to implement the same method by default (without preload / loading hooks).

Either way, I thought this was pretty cool and wanted to share.
Run npm update print-js to get the latest version.

Now that the remote file can be promised, I think the document should prompt the server to set Access-Control-Allow-Origin: *

This worked for me. http://plnkr.co/edit/kxn1TuoP9Dxj75jrdl5W?p=preview
Vue.js(http://localhost:8083) + laravel (http://appapi.test/)
Thank you @crabbly
