We commented appending image functionality in receipt print.It is working 
fine.But we have to print image on receipt.

Download 1.7.8 and take a look at that approach for appendImage.  The while 
loop is most likely causing the crash and 1.7.8 has a much better approach at 
the appendImage snippet.
