If I understand you basically want to use your phone like a terminal to submit a print request from the floor. I also assume the printer are located on the floor as well. I suppose you could create an app for the phone as long as you have the staff that can handle the coding needed. We had a issue with inventory labels and tickets. We just got some scanners with a display screen that emulated the i-series.
We created our interface that called a custom program upon login. That was much easier,cheaper and quicker to develop.
