Here's a trio of tempting inkjets compared: HP Photosmart Pro B9180, Canon PIXMA Pro 9500, and the Epson Stylus Photo R2400. I've previously reviewed the HP B9180 and the Epson R2400. The folks over at photo-i have put together a little side by side comparison of the Epson, Canon, and HP offerings. It's an interesting approach that concludes with the HP B9180 getting a slight nod. If you're in the market for a serious, but affordable large format printer, you might want to take a look.
