Digital BW, The Print

Hi all

This is my first post although I have been reading the forum for 
some time. Until recently I was a diehard darkroom worker of some 
twenty years and felt pretty negative towards digital. But I have 
been inspired by the forum and particular thanks to Clayton and Paul 
for all the info on their sites.

So I have just made my first print with an Epson R220 and MIS UTR2 
inks and have a question. I decided to do a BO print and understood 
from the forum that the print dialogue box should have a checkbox 
for 'black only'. If it said 'grayscale'as mine did, then you had to 
download the latest XP driver from the Epson website - 5.5A. This I 
did more than once and it still showed 'Grayscale'. I phoned Epson 
technical (UK) who said there was no difference between black only 
and grayscale.

So today I made a black and white print using all the colours as per 
Paul Roark's method (with grayscale box unchecked) and the resulting 
print appears virtually identical to the BO print (or was it BO). So 
should I have 'black only' in that box? I would be grateful for any 
help.

Regards
