Since you're using iQueue then the problem is not in the working space
profile or output but in the creation of the documents. Using rgb fringe
colors is not a good idea. The Fuji prints beautiful deep reds yet the Adobe
98 space can contain most usable colors for this printer.

Here's some of the advantages of matrix working space profiles. There are no
lut tables to add weight to the embedded profile. The rgb=grey remains true
throughout all you're color corrections. Everyone that has recent Photoshop
have this profile built in. Speed of color conversions. Archives well, and
is becoming a defacto standard for quality images, in a default sort of way
with Image Bank and other photo libraries. Less quantisize errors
(unavoidable according to Bruce Fraser).
So you can do it by forwarding to the printer space but there are fewer
advantages than to use a universal working space.
