[Barcode4j-users] Problems with printers and Barcode4j

[<eva...@gm...>]

Hi. My name is Fernando. I'm using your codebar generator Barcode4j. It's
work fine. But when print the image into a card printer, it's not ok. I send
the image that print with HP Laserjet 2420dn and the image with a Zebra 330i
printer. When I print with hp printer, it works fine, but when i do the same
with Zebra printer, the codebar reader can't read it (the bars are more
wide).

My code is:

public static BufferedImage generarCodigoBarras(String codigoLegible, String
tipo) throws Exception {

        //tipo = code39

        Model modelo = new Model(tipo);
        modelo.setMessage(codigoLegible);

        BarcodeGenerator gen = modelo.getBean();

        BitmapCanvasProvider provider = new BitmapCanvasProvider(300,
BufferedImage.TYPE_BYTE_BINARY, true);
        gen.generateBarcode(provider, modelo.getMessage());

        provider.finish();

        BufferedImage barCodeImage = provider.getBufferedImage();


        return barCodeImage;
    }



public class Model {

    private String msg;
    private String lastType = "none";
    private AbstractBarcodeBean bean;
    private BarcodeClassResolver resolver = new
DefaultBarcodeClassResolver();
    private List changeListeners = new LinkedList();

    public Model(String tipo) {
        this.msg = "";
        setup(tipo);
    }

    public String getMessage() {
        return this.msg;
    }

    public void setMessage(String msg) {
        if (msg == null) {
            throw new NullPointerException("Parameter msg must not be
null");
        }
        if (!this.msg.equals(msg)) {
            this.msg = msg;
        }
    }

    public AbstractBarcodeBean getBean() {
        return this.bean;
    }

    public void setup(String type) {
        if (type == null) {
            throw new NullPointerException("Parameter type must not be
null");
        }
        if (!lastType.equals(type)) {
            Class clazz;
            try {
                clazz = resolver.resolveBean(type);
                this.bean = (AbstractBarcodeBean)clazz.newInstance();

                this.bean.setModuleWidth(UnitConv.in2mm(1.0f / 200));
//with 300 the code isn't readable.
                this.bean.doQuietZone(true);
                this.bean.setFontSize (0);

            } catch (Exception e) {
                this.bean = null;
                e.printStackTrace();
                JOptionPane.showMessageDialog(null, "Error al crear el
modelo", "IMD", JOptionPane.ERROR_MESSAGE);
            }

            lastType = type;
        }
    }
}

I don't know who to make that printer impress the correct codebar!!

Please, somebody who can help me!

Best regardas and thanks in advice.

PD: sorry for my english.
PD: if somebody wants see the images, send me an email.
