Digital BW, The Print

Hi,

I posted this in the Epson 4000 group but didn't get many responses so I thought I'd try here.

I apologize if this has been addressed previously, I searched and nothing came
up!

I inherited a 4000 that I'd like to convert to B&W printing. What is the current
"best" solution? MIS? Piezography? Or is there a replacement color ink solution
that can be RIP controlled to produce both b&w/color prints?

I realize that this can be a can of worms topic, but I was hoping that there would be an obvious "just get this" solution at this point for such an old printer.

Thanks,

Nick
