Hi

I just thought i might try laser printing with aluminium foil.
I thought if i only use thin stripes of foil across the page it will not 
short out anything.
it worked witn 1cm *10cm.

it worked with 2cm *10cm.

it worked with 10cm * 10cm.

i didn't try full page but i reckon it works to.

explain.



Why the hell did it print on the aluminium foil?
simple standard kitchen foil.



(i tried with a old toner cartridge containing tha drum also, the sharp 
edges could possibly harm the drum.).



looks promising printing on copper, doesn't it?
