Not used it myself, but have heard good reports. 
The problem I can see with this type of method over normal
photographic methods is that the stuff you put through the printer is
the expensive bit, whearas with photo-etch, the expensive bit is the
coating on the PCB. 
This can be a problem if you do small PCBS - you can easily cut
photo-pcb down to the right size, and the offcuts will be useable, but
you usually can't put anything smaller than an A5 sheet though a
printer, so there is a lot of potential waste, though I don't know how
the relative costs per square whatever work out.
