Thanks Paul for your response.  The only reason I had the courage to
embark on this B&W endeavor and buy a new dedicated printer, ink,
paper etc. was because of the info at your website.  

I can only see 2 setting for gamma in the print driver; 2.2 and 1.8. 
I tried several test prints with 1.8 gamma which were also quite dark
using the QTR_260 Ilford Ilford Galerie Smooth Pearl ICC.  When I went
 to Let Printer Control Colors in PE6 I did get a lighter print with a
gamma of 1.8.  Adding brightness of +10 in the printer driver gave me
a very good print.  I can live with this.
I have some neutral ink on order from MIS and will try that to see if
the ICC works better with the neutral ink.
Thanks again    Dave
