Unable to print through Java program

Question

Hi all,
I have downloaded a sample java code to print text. When i try to print on solaris, it displays some postscript characters like:
%! PS-Adobe-3.0%%BeginProlog/imStr 0 def /heximageSrc....
But i am able to print the same information through lp command correctly.
I am using EPSON - LP8200. As per my knowledge, this printer doesn't support postscript printing
The sample java code works perfectly on Win2k connected to the same printer.
Please help me out. I am stuckup in this problem for quite a few days
Below is the code that i am using
