Your server not added ORIGIN headers. You need add it on .htaccess. For example:

Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

Or you can add it in PHP on print.html (if you can use PHP on html files)

header ("Access-Control-Allow-Origin: *");
header ("Access-Control-Allow-Headers: origin, x-requested-with, content-type");
header ("Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS");
