Just throwing this idea out there - I am actually going to try it
this week for a double sided LAYOUT

1. print 4 images on the laser printer
image 1=component side mirror
image 2=solder side
image 3=copper pour of the length of the board
image 4=copper pour of the length of the board

You can eliminate 3 and 4 if you are careful.

Many years ago in my youth I made double sided boards one at home one side
at a time as you describe by floating the board on the surface of the
etchant. Ferric chloride has quite a high surface tension and it if fairly
easy to float the board on top of it. It is even possible to agitate it a
bit if you are careful. If it sinks, no matter so long as you fish it out
again quickly.
