Hi, do you guys now know the timing/protocol of this printhead? I briefly went through this thread and found a lot of LA capture and discussion. If I missed something, please point me to the conclusion page. I'm thinking, if you don't mind, I can probably programme my ink jet controller to support this head.

In the Netherlands there are several resellers that carry them as well. I usually buy them there.

Not yet. Page 4 or 5 I think has a summary, but there is no conclusion yet on how to drive it. I am finishing up some small projects that I did not have time for because of the turret, then I will pick inkjet up again and the HP84 is around the top of the list. I will post when I have conclusions (or if I failed)

by the way, I think that a driver for this head would be very easy to adapt also to HP11 heads (C4810A, the ones used by 3DSystems Projet660 - definitely suited for 3DPP). Same number of pins and from the photos they look *exactly* the same, both outside and inside :lol:
