It would be best to do this with LayOut. Create the required scene(s) in SketchUp and make sure you have set the camera to Parallel Projection. Then send the file to LayOut and set each viewport to show one of the scenes. You can set the scale in the SketchUp inspector window in LO.Drag the edges of the viewport as needed if you need to adjust the size. Add any text, dimensions, etc. and then use File>Export>PDF to create a pdf file that you can then send to the printer.
