Jon,
Unfortunately it is not as straightforward as connecting a printer to a phone. There are 2 ways to accomplish this. The first is with the browser and a desktop plugins (so not the phone), like
https://qz.io/. With the phone and app is needed to send a POST request to the printer to print. Assuming by "portable printer" you mean a Zebra or Star type printer, right.
