 Yes they are driver options, but I can use custom printer profiles with other 
applications e.g. even printing from Firefox.

Driver options are dependent upon the printer used. What are you using?

In GIMP is see two ways: 
Image/Mode/Convert to Color Profile... lets you apply a color profile 
to your image (recalculates the color values of the pixels to make 
the image look the same with the new profile, considering the 
rendering intent). Note, that your image is connected to that color 
profile then - to avoid restricting your possibilities you should 
keep a device-independent color profile, like sRGB or AdobeRGB etc 
and thus not overwrite your file with the converted version. 
The safe way: 
On OSX you can assign a color profile to your printer with ColorSync. It's 
shipped with OS X and you find it in Applications/Utilities. 
After that in GIMP: 
Normally this should be enough and after printing the file from GIMP 
it should look as expected. 
For soft proofing: 
In the menu GIMP/Preferences/Color Management enter your profile in the 
field 'Print Simulation Profile' and choose a suitable Softproof rendering 
intent. For softproofing on the screen go to 'View/Display filters...', add 
'Color proof' to the right list. In the field 'Profile' 
in the lower part of the dialog you can choose your printer profile 
then and set a suitable Rendering intent. (Anyway I haven't seen 
the values from the Preferences dialog used as default here - I don't 
know whether this is intentional). 
Kind regards,

Where do you see this? I checked back with GIMP 2.8.4 and only saw the 
options 'Keep embedded profile' and 'Convert to RGB workspace'. 
Both are for the cases you open a file which already has a profile. 
 > Also, Image/Mode/ has two options; Assign and Convert 
The 'Assign' function is for scenarios where the file comes without 
any color profile information and you want to prepare it for a 
color management workflow. For instance if you have an image from 
the web you can often assume that it is in sRGB color space and 
thus you assign the sRGB color profile to it.

In the printer dialog in GIMP/OSX I don't see neither something related 
to color management nor the options you mention. 
Could it be they are printer driver options? In this case you would 
surely have more luck if you search the web for manufacturer manuals, 
forums or contact the manufacturer directly.

I'm sorry to say that I got error 404 ;-(

Nice that I could help you at least a bit ;-) 
You'll surely have more luck if you post directly to the mailing list as 
it increases the chance to find somebody who can help you with your 
issue. Also telling the manufacturer and model name of your printer 
would help.
