To get high quality printing with good inkjet printeres like r2400 and r2880 
here are the main steps I follow:

1. Define the colour space (e.g adobe rgb 1998) to be used when the image is 
being captured.

2. Shoot using the correct white space setting for the scene.

3. Load onto the computer having first profiled your monitor.

4. Use your  preferred editing software (e.g. photoshop) using a defined 
working space colour profile e.g. adobe 1998 (I prefer prophoto which is  
32bit floating decimal point).

5. Convert the colour profile of the image to the working colour space.

6. Process the image.

7. When processing complete choose the paper for printing.

8. Make sure you have a suitable colour profile for that paper for your chosen 
printer.

9. Print using the appropriate paper profile.
