I have done this, except I used a matt spray on plastic to coat the printout.
It gives pretty good results and includes a UV filter. Printing out on glossy
paper gave nice bright colours but the spray on coating started to come
off after a few months. I tend to use 100g paper the colours aren't as
bright but it does give a slightly diffused image ( not blurred just smoother
To stick the paper onto the front panel I used to use a paper adhesive
to glue the paper to a sheet of adhesive labels. This works ok but has
a big drawback in you only get one (maybe two) chance to get the paper
in the right place on the panel. Any recommendations for a good paper
to metal glue?

I found it is difficult to get all the paper removed from drilled holes.
There were always tiny frayed bits. Maybe I should have spent a bit more
time trying to cut them out. The upshot of this was that all devices I
would normally just stick through the front panel (leds) needed covers
to make the panel look tidy. Maybe I'm just too fussy.
Another problem can be if you ar doing a panel larger than the paper size
you have to split the design up. I found it best to do this at natural
points in the panel design ie where you have a dividing line, this helps
to hide the join.
