The autorouter can be setup to route on one particular layer only by defining a Routing Layer design rule with the following details. Basically, all unused layers need to be set to 'Not Used' and the routing layer is set to 'Any' or other suitable routing direction.

For example, to assign the bottom layer as the routing layer, use the following setup.
Top - Not Used
Bottom - Any
(Note - By default a PCB will have Top and Bottom layers and this is why you need to set the Top layer to not used to avoid routing on this layer).

To get the actual size printed, you need to make sure that "Fit Document on Page" is NOT selected. You need to select "Scaled Print" and select "1.00" as the scale.
