A board prior to etching. This is where I noticed the problem as regards to the lack of mirroring. I use toner transfer method via the cold process(i.e. mix acetone/alcohol, coat the board, apply paper, clamp, wait, remove paper under running water)

One of my early attempts. Looked fine until I noticed that I had failed to mirror the image prior to printing... Arrgghhh

An early attempt to print out a PCB. Then I noticed that Eagle had not included some pads, no vias or no contacts. That took me a little while to hunt and cure.
