While Canon printers are outstanding in most regards, longevity is not
great.
The only Wilhelm-Research reference I could find was an old report for
the Canon S900 6 cartridge printer. Using Canons longest lasting
paper and Canon ink, the lifespan was estimated at 27 years. After
the "gas fade" debacle of a few years ago, these tests were redone
with added tests including gas fade. These tests produced much more
modest results with some die based prints fading within a few days to
months. I could not find these on his site.
Another site,
http://www.livick.com/method/inkjet/pg2d.htm , lists the
Canon S9000 with various paper tests below. To be fair, none of the
Dye based printers do as well as pigment based printers for any
manufacturer. Fortunately, Epson has several long lasting printer
choices at different price points for those serious about longevity.
