Homebrew PCBs

I am still interested in an older thread on using inkjet printers to 
directly print resist.  I think the thread just died out but it sure 
seems to me that if we could find the right kind of ink, it ought be 
a really great way to get very quality/repeatable etch masks on 
copper.  I would not at all mourn the passing of the transfer 
process...

I've got an old inkjet gathering dust that I may save from my 
robotics experiments...
