Barcode Integaration with navision

The barcode printer which we are using is Intermec easycoderF4 barcode lable printer.Currently we do not have Ribbon for the printer so we are doing trials in hp laser jet2100.

The driver for easycoderF4 bacode printer is installed to my system and made as default printer.While printing the generated barcode from a report ,i am selecting hplaser printer with barcode printer driver.

In preview of the report only the paper size is varying but barcode is not printing.

Can u suggest in this regard???

Should i need to install anyother things in regard to this, like fonts??

We are new to barcode interface with navision.
If anybody knows pls tell wat are the steps we have to go about accomplishing this task of printing barcode number from navison :-((
