Digital BW, The Print

Hi all !

just recently joined this group and I am amazed by the number of 
threads !

I serioulsy look into buying a EPSON PRO 4000 here in Singapore for a 
price of 3500 SIN$ (about 1640Euro or 2140$).

Is in terms of bw printing ok with the default inks or is a 
replacement of the inks by pro bw inks required ?

Thanks for your tips.
