I want to print a table a little differently than it is displayed on the screen of the user as I want to resize the table so that columns fit on 1 page. To do this, I copied the main table into a new table by using newTable.refresh(oldTable.getDataVector()) Then I changed the columns and stuff of newTable and did newTable.print() - I got only blank sheets of paper. Later, I tried putting newTable in a JFrame using the following code which worked: JFrame frame = new JFrame(); frame.getContentPane().add(newTable); frame.show(); then, newTable.print(); //This time it works!!! Is it neccessary to put a DBTable into a Frame to be able to just print it? Is there a way around this? --------------------

If the component is not visible, you cannot print it. There are some workaround 1) create the temporary frame outside screen coordiantes, so users cannot see this JFrame frame = new JFrame(); frame.setBounds(-200, 0, 200, 200); frame.getContentPane().add(newTable); frame.setVisible(true); 2) try calling newTable.addNotify() (without adding to frame) & then call print. If this doesn't work then add newTable to frame , but without calling show() or setVisible(true); call newTable.addNotify() & then call print. If this works, please share with us which solution worked.

Here's the code I used: //table has the dbtable which needs to be printed JFrame frame = new JFrame(); //create dummy frame frame.getContentPane().add(table); //add table to dummy frame frame.show(); //show the dummy frame frame.dispose(); //remove the dummy frame table.print(); //print the dbtable - this works even after the above frame is disposed --------------------
