I'm in need of a replacement for my Canon Pixma printer.

My main criteria:
1. Automatically duplexes
2. Separate cartridges for each ink color
3. Network printer
4. Wireless

Number 1 and 2 are a must. 3 would be beneficial but not totally necessary. 4 would be OK if all other criteria are met first.

I'm looking at HP and Canon. I've had a lot of Canons through the years. I've always been frustrated with their photo quality even on well rated printers but.....I also use after market ink and that may be a part of it.

I'm leaning toward HP at this point and have a couple that I've narrowed it down to:

1.  HP Officejet Pro 8000 Wireless Printer

2. HP Officejet Pro L7590 All-In-One Printer

 I don't necessarily need an all in one but the price is right

3. PIXMA iP4600 - this one doesn't network but meets criteria 1 and 2

From what I've read, I think my cost per page would be lower on the HP printers but I can't find real costs on the Pixma.

Any suggestions would be appreciated.
