The printer has to plug into the express or into a Mac..

phones cannot print except to airprint compatible printers.. so you need to run a computer.. with a special APP.. like Printopia.. if the Express doesn't work then plug it into a computer and use printopia.

Or .. mail the document to yourself and print from a real computer.. !!

iOS is very limited when you want to do real computer stuff.. unless you pay all the necessary cash for special printers etc.
