I tracked down my NSView printing problem to the NSPrintPanel preview view. My view printing now works again by overriding the default option to display the small preview view: def print po = NSPrintOperation.printOperationWithView( @printableView ) po.printPanel.setOptions( 0 ) po.setShowsPrintPanel( true ) po.runOperationModalForWindow( @printableView.window, delegate:self, didRunSelector:"printOperationDidRun:success:contextInfo:", contextInfo:nil ) end def printOperationDidRun( printOperation, success:success, contextInfo:contextInfo ) puts "printOperationDidRun #{ success }" end or I can bypass the printPanel entirely. It will take more experimenting to find out why NSPrintPanel is not creating a graphics context for my NSView or why it would call my drawRect with an invalid context; it works with my PDFView. But now it's a low priority for me since I don't really need the NSPrintPanel preview. Bob Rice
