hi friends, I am developing an Android App that connects with a Bluetooth printer for printing the data mostly receipts(its a thermal printer). I have googled it
and found the code which I am posting in the below link .
 
http://pastie.org/6108587 and this link also http://pastie.org/6108619
 
I was able to detect the bluetooth and even got the MAC address and the printer name. but when I
 
send the data to the printer it is throwing as Timeout exception and some time as Null Pointer exception.
 
I am sending byte array as data to the printer but the printer is taking too much time to receive the data. I dont know why this is happended and I used the
 
following code to connect and print the data. Is this code is correct? If not is there any other way to connect to the printer.
 
Thanks in Advance
Ganesh
