How to Print ZPL or CPCL codes directly vis USB

Hi my printer model is a Zebra TL2844 connected to a Windows 8, i am developer and print from Delphi or Visual Basic, i generate the report (labels with code bars), in print preview, of course i can send directly to printer via report (no preview) but not like me use the reporter, i think would exist a way for print directly the ZPL or CPCL codes, directly to usb printer, how to?

 

can anyone share with me C# and Java(with a Servlet) code for test?

 

thanks

 

my label:

 

<CodeBar>

100-001

 

 

Thanks
