thanks for reply Daniele,

I change my code and put the whole body of main method in a try block
and remove the throws PrinterException clause from print method declaration.

Finally I put the body of print method in a try block.


I execute my code again but the console not output any error message.


I type 
java -Xmx1024m TestPrinter2

in console window to execute the code.
