color managment MP 750 using gutenprint

[le boff]

Hello
I am using Canon MP 750 from several years with pleasure.
Now moving to Mavericks, this OS doesn't handle MP 750 (too old printer)

So I installed today gutenprint 5.2.10a on Mavericks.
Printer is found and I can print .
B&W prints are good,
but color prints are dull : red is pink and so on

Then I tried all avalable icc profiles in color managment: sme results

I going back to Snow leopard, where MP 750 is propperly handled, I find a .icc
named Canon MP780 SP2.icc and copy it in Mavericks/Syst/Lib/ColorSync/
I launch a new test print, I selected this profile
same result, dull colors

So I will appreciate any help on this topic: how to recover correct colors using gutenprint
on a Canon inkjet MP750

Thanks

Bernard
