If the selected image is not displayed in the image cell of the print preview, it is LR that is screwed up, not the printer driver. Are you sure that an image is selected? Is the selected image displayed in the loupe views of the Library and/or Develop module(s)? In Print, when one of the bundled templates is selected, is the image displayed? At the bottom of the preview pane, where it says "Use:" is "Selected Photos" selected?
