I have owned the 9000MKII and now own the Pro100. In my opinion it is well worth the upgrade. I only print on Ilford or Canon semi gloss paper; which works very well for both printers. Specifically to the question of B&W printing, the Pro 100 delivers in spades and matches exactly what I see on the screen; I use a calibrated Dell U2410 IPS monitor. I enjoy using the printer so much, I have spent the last couple of weeks mining my old photos to find new stuff to print. With the 9000MKII, I was not able to accurately print what I saw on the screen to the extent I can with the Pro 100 and the 9000 also struggled with clouds . The Pro 100 always ends up being a very close match with color photos and a perfect match with B&W photos.
A couple of other highlights that should not be missed about this printer; Canon Print Studio Pro, WIFI, and 16 bit XPS printer. The Canon Print Studio Pro plug-in makes it really easy to print from LR or DPP etc; it's a simple, fast and fluid interface that gives the essential options you need for getting out your prints; it even allows you to make on the fly ICC, color/tint, cropping adjustments before sending to print. WIFI is self explanatory. Before Print Studio, I always had to load an image in LR to print (didn't trust anything else); now I can simply open up a jpg in DPP, call up the Print Studio plug in, make any necessary and non-destructible adjustments and hit print.
The 16 bit driver allows you to capture even more subtle tonal variations in your images especially when directly printing from Raw files in Light Room; the advantages of 16 bit printing are not always apparent but when you are trying to nail down a skin tone or the tint of B&W or Brown in a print you need every advantage you can use.
If you are on the fence about this printer, take the plunge. Its worth a lot more than the post rebate price and a more than worthy upgrade to its predecessor.
