Addendum to my Canon i9900 printer review

I've had my Canon i9900 for a while now and I've noticed the colour output isn't what I'd expect.  Initially I suspect there was a setting I needed to adjust and I experimented trying to fix it, but to no avail.  I contact Canon and they had me tweak all the settings and it still made no difference.  Finally I ran a test myself - I created an image with a gray square (RGB(204,204,204)) and printed it out at the default settings - the result was a blue square.  I told the printer to print it in grayscale and got the expected gray square.  I sent a photo of the output to Canon which convinced them something was wrong and they told me to take it to a local service center.  I was prepared to do that until I noticed on their website that the printer is covered by an “InstantExchange” program.  I asked them about this and they apologised for the confusion and I should receive a replacement printer in a few days.  They told me to keep the print head though, which is a slight concern as what do I do if the fault is in the print head?

If anyone has some recommendations for glossy 13”x19” photo paper I'd like to hear it.  Canon's Glossy Photo Paper is good, but I prefer the look I get when using the 8 1/2” x 11” Photo Paper Plus Glossy which doesn't appear to be available in 13”x19”.  If you've used their Photo Paper Pro 13”x19” I'd be interested to hear what you think.
