The established and most used methods currently are tiner transfer and
photo process.
Inkjet printing is something we are still working on, but i wouldn't see
why someone couldn't jump right into it.

It's basically all about the ink, Volkan found one that works, MISPRO
yellow, at inksupply.com.
It's also about the head, you need a newer printer with many nozzles. See
previous posts for example models, but all the newer ones with variable
drop size should be the right kind..
You basically figure out a way how to feed the PCBs through the printer
and you also need to cure the ink before etching with heat, a stove plate
works, when it starts to turn brown it is enough.

As you see, there isn't terribly much known about this so far. But i'm
confident everyone can duplicate it. I took me so long because i had the
wrong printer at first. With the right printer, and the right ink in the
cartridge, it basically worked within 5 minutes.
