The Krita printer color management proposal has been accepted into the 2012 Google Summer of Code!
The initial phase of this project will actually begin right now – it will involve fine-tuning the libCmpx interface, looking over the possible areas of integration in Krita, and formulating a game plan with my mentor and the key people involved with printing and color management. The official coding period begins in late May, so there is time at the moment to lay down a three-month strategy.
This project will be a huge undertaking for me, especially since color-managed printing under Linux is essentially on the cusp of becoming a reality. But I will do my best in the coming months!
