Add support for direct print to PDF-file.

Thank you for the PR. Could you change it so that instead of writing the file, it returns the file as a response?
Then we can return that file in the PHP API and the user can decide what they want to do with it - and potentially save it.

Should I return the PDF-data as a base64 encoded string?

Yeah I think this would be the easiest option
