title: Creating PDF file from remote URL with jsPDF
body: <p>I'm struggling with this problem for quite a while and wanted to ask for help.
  I'm trying to generate a PDF file from a <code>remote URL</code> in <code>PHP</code>. 
  for example from <code>mysite.com?id=12</code> so when I click on this link the <code>browser's pdf viewer</code> opens with the contents of this URL <code>including all styles</code> etc.
  I've tried it with <code>jsPDF</code> javascript library but it seems that it can't be used for remote URLs. I also found tons of libraries which all need API keys ( registration, subscription, payment ....).
  I don't want to ask for code samples but just for instructions on which library is able to do that and the workflow.
  Thanks in advance.</p>
