I don't know why, either. I've dabbled with TT but it just seems too much
like hard work, whereas photo-etch works every time with the minimum of
fuss.

I think that the main problem is still going to be the ink. Professional
systems using ink jet technology use special ink with very expensive
printheads, with UV curing directly after the ink is deposited. Also,
double-sided boards will always be problematical with ordinary printers.

I heard of a new inkjet technology for PCBs on the radio recently that uses
conductive ink which is being developed here in the UK. It's still very
experimental. It's probably similar to this Epson system:
