Digital BW, The Print

Dear all,

Using osx 2,8, epson p2100,
 The various sites dedicated to info have not helped me get beyond my
problem:  QRT 2.1 software and curves for Epson p2100 using osx 2.x with
gimpprint and ghostscrip all seem to be loaded correctly.  Gimp and qtr are
in printerlist.  Ultrachrome curves are in qtr settings in print dialogue as
loaded from install 2100 in profile folder.  Why, oh why, does nothing
print.  Error message: GenericClass: Waiting for Device.

I know you know what I'm talkin about
Sheesh!
