Brother Mobile SDK Printing From Custom IOS Application

Question

I created an IOS Application to print Labels from a QL-820NMBc. Everything works exactly as intended code wise. However, the only way I can get the Label to finally Print out of the printer, is to Force Close the Mobile Application.

I am in no way a network GURU, but I feel that something is blocking the data from the Ipad to the printer to finalize the print. Just a guess.

Any help would be appreciated.
