Printing with POS Printer

[A.G Rajkotia]

Hie,

I have been working on a Billing Application and now its almost complete. I'm stuck on printing the bill. The problem is that when i print the bill on my normal printer (A4 Size paper) it works fine, but when I print it on a POS printer (Epson LX 300+), I get some strange printing. Are there any special API for POS Printing. Any tutorial, code, help on POS printing is welcomed.

Thanking you in advance,
A.G Rajkotia.

How are you printing it on the POS printer and what exactly is going wrong; is just the formatting wrong (maybe because the paper isn't as wide as an A4)?

I'm using java.awt.print library . part of code is given below

PrinterJob job = PrinterJob.getPrinterJob();
        job.setPrintable(bill);
        try {
                job.print(attr_set);
            } catch (PrinterException e) {
                System.out.println("Problem occured in job.print()");
            }
    }
}

Code inside the Bill class is like this

public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {

    // This is the table I need to print
    table.print(JTable.PrintMode.FIT_WIDTH, null, null, false, null, false, null);
}

This prints the table well with the normal all in one desktop printer, but when i use the POS printer, letters are too closely printed making it difficult to read. I tried new JTextArea("Hello World").print(); but still got the same results.

Its a 9 pin dot Matrix Printer (Epson lx 300 + ii) . Is there anything to do with the font ?
