printing only filled data from JTable with logo

my program hava a JTable with 100 blank rows. Let user fills only 10 rows. Now he want to print only the filled rows with a logo on the top. How to do it ?

Here is the code i used:

if(e.getSource() == print){
    try {
        table.print(JTable.PrintMode.FIT_WIDTH, head, null); 
    } catch (java.awt.print.PrinterException e1) {
         System.err.format("Cannot print %s%n", e1.getMessage()); 
    }
}

It simply prints all the 100 rows.

I want to print only the filled rows( let first 10 rows get filled)

you can filter the empty rows before printing:

table.setAutoCreateRowSorter(true);
RowFilter filter = new RowFilter() {

    public void include(Entry entry) {
        // here add a loop which checks if 
        // any of the values in the entry is not-null
        // return true if yes, false otherwise (that is all empty)
    }
};
((DefaultRowSorter) table.getRowSorter()).setRowFilter(filter);
table.print(....);
