Brief, practical guidance for (and to correct the unhelpful quips from and ): printing a selected set of rows from a Swing table for a passbook printer is best solved in one of three ways depending on how much control the printer needs.

Option 1 — quick: build a temporary TableModel containing only rows where the boolean "print" column is true and call JTable.print(), which handles pagination and headers. Example (copy rows into a DefaultTableModel and print the temporary table):

DefaultTableModel src = (DefaultTableModel) originalTable.getModel();
DefaultTableModel tmp = new DefaultTableModel();
for (int c=0; c<src.getColumnCount(); c++) tmp.addColumn(src.getColumnName(c));
for (int r=0; r<src.getRowCount(); r++) {
    Object flag = src.getValueAt(r, printColIndex);
    if (Boolean.TRUE.equals(flag)) {
        Vector row = new Vector();
        for (int c=0; c<src.getColumnCount(); c++) row.add(src.getValueAt(r,c));
        tmp.addRow(row);
    }
}
JTable printTable = new JTable(tmp);
printTable.print();

Option 2 — precise layout: implement Printable and use PrinterJob when column widths, fonts, or continuous passbook paper must match exactly. The Printable implementation draws text with Graphics2D, computes line height from FontMetrics, paginates rows, and uses Paper/PageFormat to set imageable area.

Option 3 — raw device control: if the passbook printer expects ESC/POS or manufacturer-specific commands, send raw bytes with javax.print (DocFlavor.BYTE_ARRAY.AUTOSENSE and SimpleDoc) to the target PrintService. This requires the printer manual and exact command sequences.

Troubleshooting notes: test layout by printing to PDF first; run printing off the EDT (SwingWorker or background thread); verify the "print" column contains true Booleans; set Paper size and imageable area to match the passbook; and test on the real hardware—many problems are printer-protocol or margin-related rather than Swing code.

Given your description (the lack of description that is), you may use a System.out.println.

Again, refer to javaaddict's post for more information on why nobody is helping you.
