Homebrew PCBs

If someone was looking to build a standalone x,y printer with an inkjet 
head, without dealing with gutting and hacking an inkjet printer - here 
is the link for the development kit:

HP thermal technology.  since the head is on the cartridge - it makes 
it a little easier to maintain or fool around with.

And I dont know if this matters, but I believe pitnet bowes, or 
ascom/hassler uses this same setup to print postage on the ultra-fast 
metering mail machines; which I am pretty certain is an indelliable ink 
which isnt water soluable.
