    norm i think im screwing up here :/..

    i wanna start from the beginning.

    public class Printer implements Printable{
     
    public static void main(String args[]){
     
    }
    public int print(){
     
    }

    So to begin with, i will need a text area where the user will type in. But for now we can use a String variable.

    public class Printer implements Printable{
    String textPrint = "test" //assuming the next test will be on a new line
     "test2";
    public static void main(String args[]){
     
    }
    public int print(){
     
    }
    }

    from my last post. how would i start the print method?
    keeping in my mind:
    Must print multiple lines
    Must print multiple pages
    Must print within its borders.

    So can you guide me through this problem please?

    Create a special test program to work out the logic. Create a class that extends JPanel, override its paintComponent() method and add an instance of it to a JFrame so you can see the results.
    In the paintComponent method, add code that is almost exactly the same as the code in your drawString() method. Have the code take a String with \n characters, split it and draw the substrings that are in the array returned by split using the Graphics drawstring() method in a loop where the value of the y location is increased each time around the loop.
    If you don't understand my answer, don't ignore it, ask a question.

    could you go step by step with me?

    ok so, made the GUI:

    public class Frame extends javax.swing.JFrame {
    String textPrint;
        /** Creates new form Frame */
        public Frame() {
            initComponents();
        }
     
        /** This method is called from within the constructor to

        // Variables declaration - do not modify
        private javax.swing.JButton Print;
        private javax.swing.JScrollPane jScrollPane1;
        private javax.swing.JTextArea text;
        // End of variables declaration
    }

    So where to from here?

    What is all that code for?
    Reread my suggestion in post#29. There are two classes: JFrame with a main() method and JPanel with a paintComponent() method. No more.
    If you don't understand my answer, don't ignore it, ask a question.
