Need Help in barcode display

Hi,

I have to display barcodes on screen.

I am able to display barcodes on screen. But when I take a print out of that and try to scan, the barcode scanners/readers are not recognizing the barcode.

Implementation details: I created barcode using iText and converted it into awt image and displayed it using Graphics2D.

Is my way of testing is right? Are there specific printers to print pages like this which contain barcode images?

Any pointers would be helpful.

Thanks
strive

Can a barcode scanner recognize the barcode when it is displayed on the screen? Most modern telephones have a barcode scanner app included or can be equipped with one for free. If this works, it would narrow down the error source to the printing itself.
