Thre are two options, both require obtaining the ICC profiles from the=20
printer manufacturers (included in their windows drivers, and sometimes=20
as a separate download)

Then, you can either:

 * Pre-process the source images with the profile before you submit them=20
   for printing.  (Since you're already using ImageMagick this is easy)
 * If your distribution uses colord (and CUPS is also built to use it) then
   you can import the ICC profiles and associate them with your printers us=
ing
   colord's tools (eg colormgr).  CUPS will then do the right thing automat=
ically.

In both cases you'll need to submit a "color" image because even if the=20
channels are the same going in, they won't be the same by the time=20
they're submitted to the printer.
