I use this method extensively and have had very good luck even to printing lines and spacings less than 10 mils.  The secret is clean clean clean the board..   If you didnt get it the first time let me reitterate it.. clean the board.

The way to do this is ..

1st - use a very fine scotch brite with dish soap and scour the board until it is bright and shiny.  
2nd- rinse the board with water and wipe with with MEK 
3rd- use the scotch brite again and scrub the board a second time.
4th- rinse the board with water again then submerge in the board good ol' isopropal alcohol.  

Do not touch the board with your fingers use gloves (make sure the latex gloves have been washed with water and dried before you touch the board remember some gloves have powder on them) 

I use the laminator that I bought from PULSAR.  It works great.. ohhh before I forget it.. dump the HP1000 series printer and get a later printer.. the older printers dont work correctly.
