The figure on page 114 is a view of the bottom (copper) layer looking through the PCB from the top. In other words, you're looking at the component side of the board. There is no need to flip the board over. This is the same view you get in the PCB package. All layers are viewed through the board.

I forgot to mention when I said "Print" I meant with a CnC Pen plotter, UV laser plot on to dry film, or expose image on to dry film with UV projector, nonetheless I think my question was answered, If I was to use a laser printer ink transfer method, I would leave as is, but in my case, it needs to be mirrored, due to the fact I am plotting (drawing) directly to the PCB copper board and not a sheet of photo paper.

If you are cnc engraving the PCB, then (of course) you need to flip over the image. Then the components are inserted on the side where there are no PCB tracks. The same applies to the ink transfer method.
However, if you're submitting the Gerber files to a PCB manufacturer, the files remain as they are. The manufacturer knows that the bottom layer needs to be flipped.
