I'm actually working on HP Black inks right now.(The color inks just run, 
regardless how I dry/cure them) I just realized I have an old Deskjet 340 
sitting around, that already has a straight paper path. I am currently 
fighting a battle with the inks beading up on the copper, even though my 
initial tests on aluminum worked without any problems. My next attempt will 
be using a hair dryer (mild hot air gun) to warm the board during printing, 
and get the inks to dry quicker, hopefully as they hit the copper.
