As the (proprietary) Fargo supplied filter converts cups-raster to the 
printer's native format, you could try the following:

(1) replace both the pstoraster and pdftoraster filters by my gstoraster 
filter (for safety reasons, don't trash the originals) and adjust the 
mime.types and mime.convs accordingly.

(2) edit the filter script as follows:
replace the line 347 reading
push @gsopts, "-dB_W_DEVICE" if (defined $is_b_w && $is_b_w);
by 
push @gsopts, "-dB_W_DEVICE";

If that leads to the desired result, you are happy, otherwise I don't know 
what to do else.
The problem is that you cannot change the colorspace as defined in the cups 
raster header outside the raster header.
