I haven't changed the inks. I have two Canon printers. A Pro9000MKII and a 
MP540. I have changed the ink to the Pro9000 but on the MP540 I use a ink from 
Image Specialists form some years ago. All the tests are did with the MP540 and 
with the same ink then I discard any option of ink mixed.OK.

visual poblem that I see on my prints are a non neutral ramp of grays, from 
black to white. I see some grey with magesta cast and other grays with cyan 
cast.My test patch uses 64 grays. Then I suppose that it mus be prectically 
neutral on all the ramp.There may be metametrism problem. You should to solve 
the trouble with profiling fist. Then You will be able to check the prints 

is possible a error with the color management on my Windows 7 Ultimate or in 
printer driver?Yes. It can be the case.
If there is some setup for Windows color management, try to set: 

Global settings:
Device profile: sRGB IEC619...
WSC profile: for ICC viewing condition
Default renderings: Photo

Printer settings:
Profile: manual
Default profile: sRGB IEC619...

When You perform this, I hope the OS color management will not change the data 
between the Photoshop and the printer.

In Photoshop:

1. While opening the target from ArgyllCMS assign they sRGB IEC619...
2. While printing, select in Photoshop "Photoshop manages the colors".
3. Select relative colorimetric intent.
4. Disable BPC
5. Select the profile for printer sRGB IEC619...

This way You'll be able to use, but "neutralize" the color management 
behaviour. The color management will be ON and working, but RGB values will be 
untouched, I hope.
I've profiled GDI printers on Vista or 7 such way successfully.
