I am facing a string formatting issue during printing an invoice. The invoice is not properly aligned as I required.
My code is below.

public static String padRight(String s, int n) {
    return String.format("%-" + n + "s", s);
}

public static String padRightInt(int s, int n) {
    return String.format("%-" + n + "d", s);
}

public static void printIvoice(Node node){
    Printer printer = Printer.getDefaultPrinter();
    PrinterJob printerJob = PrinterJob.createPrinterJob(printer);
    double scale = 0.791;
    node.getTransforms().add(new Scale(scale, scale));
    boolean success = printerJob.printPage(node);
    if (success) {
        printerJob.endJob();
    }
}

public static Node getPrintableText(String[] products){
    Label text = new Label();
    StringBuilder stringBuilder = new StringBuilder();
    stringBuilder.append("             Company Name            n");
    stringBuilder.append("---------------------------------------------" + "n");
    stringBuilder.append(String.format("%-40s %5s %10sn", "Item", "Qty", "Price"));
    stringBuilder.append(String.format( "%-40s %5s %10sn", "----", "---", "-----"));
    for(String product: products){

        if(product.trim().length() > 25){
            String firstLine = product.trim().substring(0, 25);
            stringBuilder.append(firstLine).append(" ").append("n");
            String lastLine = product.trim().substring(25);
            int spaces = 50 - lastLine.length();
            stringBuilder.append( String.format(padRight(lastLine, spaces), lastLine) + String.format(padRightInt(1, 10), 1) +" "+ String.format(padRightInt(1000, 10), 1000)).append("n");
        }else{
            String temp = product.trim();
            int spaces = 50 - temp.length();
            stringBuilder.append( String.format(padRight(temp, spaces), temp) + String.format(padRightInt(1, 10), 1) +" "+ String.format(padRightInt(1000, 10), 1000)).append("n");
        }
    }
    stringBuilder.append("_____________________________________________" + "n");
    stringBuilder.append("Net Amount                                 5000"  + "n");
    stringBuilder.append("_____________________________________________" + "n");
    stringBuilder.append("Thank you so much!" + "n");
    text.setText(stringBuilder.toString());
    return text;
}

Here is the main method to call this code.

public static void main(String[] args) {
    String[] productName = {
            "Android",
            "Mac OS",
            "Windows 10 Operating System",
            "Linux Operating System",
            "Windows Server OS"
    };
    Node node = getPrintableText(productName);
    printIvoice(node);
}

The code output is below

I want to align the output according to product name length.
I tried to format it through extra spaces, but it’s not working. I want to align the quantity and price columns properly. Please help. Thanks in advance.
