From: Rebecca on 23 Sep 2009 22:09 I'm trying to print out my code, and pressing the print button in the Editor or choosing File/Print seems to cause a Java exception to be thrown. How do I fix this so I can print from MatLab? I'm running 2009a Student Version on Mac OS X 10.6.1 This is the specific error message that is displayed in the cmd window: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.mathworks.widgets.text.print.PrintSettings.getLastPrintRequestAttributes(PrintSettings.java:280) at com.mathworks.widgets.SyntaxTextPaneBase.printDocument(SyntaxTextPaneBase.java:2031) at com.mathworks.widgets.SyntaxTextPaneMultiView.printDocument(SyntaxTextPaneMultiView.java:750) at com.mathworks.mde.editor.EditorView.doPrint(EditorView.java:1284) at com.mathworks.mde.editor.EditorView.access$2300(EditorView.java:92) at com.mathworks.mde.editor.EditorView$8.update(EditorView.java:775) at com.mathworks.mde.editor.EditorAction$ObservableAction.actionPerformed(EditorAction.java:52) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2028) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2351) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:387) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:242) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:236) at java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:272) at java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:272) at java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:272) at java.awt.Component.processMouseEvent(Component.java:6348) at javax.swing.JComponent.processMouseEvent(JComponent.java:3267) at com.mathworks.mwswing.MJButton.processMouseEvent(MJButton.java:294) at java.awt.Component.processEvent(Component.java:6113) at java.awt.Container.processEvent(Container.java:2085) at java.awt.Component.dispatchEventImpl(Component.java:4714) at java.awt.Container.dispatchEventImpl(Container.java:2143) at java.awt.Component.dispatchEvent(Component.java:4544) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4618) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4282) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4212) at java.awt.Container.dispatchEventImpl(Container.java:2129) at java.awt.Window.dispatchEventImpl(Window.java:2475) at java.awt.Component.dispatchEvent(Component.java:4544) at java.awt.EventQueue.dispatchEvent(EventQueue.java:635) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:296) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:211) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:196) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:188) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)

I don't have any network printers, and I get the same message as Rebecca, not the one mentioned in the bug report. I also have the same version as Rebecca, and also on snow leopard.

Thanks Richard, but I don't think that's it. I'm trying to print to a printer plugged into my computer via USB. It's not a network printer at all. I've also tried the various other suggestions for dealing with (what seem to me to be) random Java exceptions - I changed the Java preferences to favour the 32-bit Java VM. I'm at a loss of what to do next though. -R

Sometimes the version of Java in use and the version of CUPS (Common Unix Printing Service) that supports printing on OS X. They may be able to help identify what's going on. -- Richard Quist Software Developer The MathWorks, Inc. |
