HI 

just make my first test on the Xerox solid ink printer 
(collor-cube 8570n)

that was shame , noting close to 2400dip claimed by xerox
this was same pcb image print wit dell laser printer (600DPI)
and whit the Xerox for comparaison (transparency over white sheet)..

only good thing is that black was really black

this was also image from Xerox print on paper of a QFN 0.5mm pitch
