    Copy the full text of the error messages and paste it here.
    Also paste the code for testing.

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    df is not abstract and does not override abstract method print(java.awt.Graphics,java.awt.print.PageFormat, int) in java.awt.print.Printable
    The df class needs to define the methods of the Printable interface.
