Digital BW, The Print

Hello to all forum members. My name is Khaled Aboumrad, I'm a
photographer, I'm 
Mexican, I live in Paris and I work in black and white. I worked as a
fashion and comercial 
photographer for many years until I got bored of it and decided to
dedicate myself 
completely to my personal work. I've been printing traditionally
since I
started in 93 and latelely 
I've tried different digital approaches with a few labs around Paris,
the problem is that it is 
too expensive and I can't have as much control as I'd like. I'm in
the process of editing a 
new portfolio so I'm looking for a way to print it with the highest
quality possible while not 
going broke at the same time.

I decided to do it myself for this reasons so I've been doing some
trials with my printer 
(R800) with no results, later I found Clayton's and Paul's websites
(which I found very 
enlightening I must say) and this forum and looked at all the posts
regarding this printer 
and it's fake BO etc. so my questions are:

1.- Is it possible to print BO using QTR with this printer?

2.- Is eboni ink compatible? Or will it clog the print heads?

3.- Would it be better to wait for the Piezo K7 inks? (Not good since
I'm in a hurry to start 
printing)

4.- Can you suggest other solutions without changing printers?

What I'm looking for is to be able to print with carbon only inks in
matte paper, as close to 
neutral as possible (a little warm is ok), deep deep blacks and
strong fade resistance. 

I appreciate any help or suggestion that you may bring and I'm
looking forward to 
contribute to the forum in any way I can.

Thank you.

Khaled
