I see that Radlafx raised this concern,

Careful with the Canon inkjet printers, they don't all use archival inks.

I rechecked the specifications for the Canon PIXMA Pro9000 ...

Quoting from the Canon PIXMA Pro9000 'Overview' tab ...

"The PIXMA Pro9000's ChromaLife100 system combines the benefits
of dye-based ink, Canon photo paper and FINE print head technology
to produce long-lasting, beautiful prints." 

When reading the Canon PIXMA Pro9000 'Supplies & Accessories' tab ...

All of the inks listed are "CLI-8" inks. 

The Canon web site has statements about the ChromaLife100 system ...

ChromaLife100 compliant ink types: CLI-8, CL-41/51/52 and BCI-16

100 years in an album

30 years lightfast

I read that to mean that the Canon PIXMA Pro9000 is capable of
producing archival quality prints.
