I found a way to set up a mobile printer to work with iPad, but it requires you have an iPad with the mobile hotspot feature. I've created a parts list and a youtube video to help you get it set up. They can be found here:

Brother has a mobile printer that we are using in the field to print invoices.  It's called the PocketJet 673.

Zebra has a mobile printer to print receipts or PDF's called the imz320.  Its 3" wide.  I use that and the app called Mobi Print.

HP released the 1200w NFC Print Accessory. It allows you to use the HP 100 mobile or HP 150 mobile with your iPad. Here is a video showing the setup: https://www.youtube.com/watch?v=9zVfCpT4X84
