Java Swing条形码创建

Question

I am developing a simple application for printing stickers and I need to print barcodes. For some reasons I need to generate barcodes as text not as images. It is all good enough with barcode creation and printing but scanner do not recognize these barcodes.

I am using JLabel component and system barcode font for it ( IDAutomationHC39M, C39HrP24DhTt ) for barcode creation. Scanner tried to recognize it (it automatically switched to constant laser mode) but there is no result.

Barcode text example 999-999999-9/9

So, maybe I missed something or did something wrong? Full explanation or link will be appreciated!

UPD code example

barcodeLabel = new JLabel("*"+hwb.getNumber()+"-1/1*");
Font f = new Font("IDAutomationHC39M",java.awt.Font.PLAIN,8);
barcodeLabel.setFont(f); 

Please ignore hardcoded "1/1" - it's for test only.

UPD printed barcode example

SOME UPDATE

It looks strange but seems that problem is in the scanner - I have tried with a laser scanner, the scanner application on my Android phone and got no result. I called it strange because the scanner successfully worked with code39 barcodes before. Now I have tried to scan with zxing-based scanner in my own Android app and it recognized successfully. I will make some experiments with different scanners during next days.

FINALLY

I have tried to scan these barcodes on two other scanners (Metrologic and Symbol) and they show perfect results - all barcodes recognized successfully. I think all problems was in my cheap scanner - it works great with barcodes printed on laser printer but if print quality is not ideal - it useless. I'm very sorry that I have started topic because of this stupid device and my own inattention. Anyway thanks for all commentators, topic may be closed.

So there was no programm mistakes only hardware limitations.
