BestColor was supposed to support it soon, but v4.63 doesn't do so yet.
The built in sensor in the HP isn't very suitable for accurate calibration
due to it only returning paper relative readings. An additional complication
is that the test chart layout is fixed, and doesn't suite systems that
need to calibrate composite C+lc and M+lm channels. The encoding
scheme used to encode the light cyan & magenta device values in
a CMYK file is also not documented, and relatively inflexible.
All in all, it's a nice idea, but implemented in an almost unusable way.
