Print Large Text IOS

Hi

have a large text to print from ios

1.i use adobe flex to print ( i have made something called adobe native extension to connect and print to imz320 on ios)

2.it connects fine

3.if i print a small text it works file

now if i print a large text the blue light on the printer blinks but nothing happens

if i put the same text and try to print the text using zebra setup utilities by putting it in a file its prints well

the same text i use it to print from Android and its prints fine without any problems

 

i have atteched the code in a text file

i thing the problem is something with IOS bluetooth

i have traced the text that recived on the ios and what is sent to the printer its the same as the attached file

does anyone has an idea
