Conclusion: The product is unfortunately not compatible with my photographic workflow requiring a additional software package to which the photographs have to be copied and pasted in order to print. As a semi-professional photographer, this is a time consuming drawback that is not necessary with other printers.
Cons: Difficult to use, Slow Print Speed, Large Footprint, Difficult Setup
Conclusion: I have a new Pixma Pro 10 and purchased it based on the many reviews regarding quality of the prints. I can't tell of course, because paper doesn't feed. Nothing is more frustrating than spending hours trying to get paper to feed to print a simple email or map much less photos! I also don't understand why the printer preference doesn't let you print from the manual tray when plain paper is chosen! So far, the printer is useless if it can't load paper.
Conclusion: The claim on this massive sized printer is that it can be used via usb, wireless, or wired LAN. It turns out it can only be used on some (granted a large percentage of) LANs. Where I work we have static IP addresses. I've never seen a printer that claims to be networkable that couldn't in some way get put on a LAN with static IP addresses. That is something you need to note in your literature and on the box. It's not networkable, it's networkable some of the times.
Summary: I would have potentially rated the Pro 100 4 stars if it wasn't for the alignment issue. after my first A3 print the photo was brilliant at first then I realized that there was a bleeding smudge on the black area of my photo, then the horizontal streaks were obvious. Bottom plate cleaning, nozzle cleaning, deep cleaning, head alignment, re-alignment over and over and over couldn't help.
