Pros: Quality of print is outstanding. I haven't done color calibrations and tested the output, but graphic quality is also very good. Warms up pretty quickly to print (not as fast as brother), isn't too noisy when printing and goes to sleep quickly at which point it is silent.
Cons: Not great for macs. I have 10.6 desktops and servers. Printing seems to work fine. Scanning to smb also works well. However when scanning from the mac desktop the file sizes are always huge and much larger than they should be (or are for the same scan from a windows desktop). I can only assume the drivers are always scanning with true color (24 bit per pixel) and displaying as B&W or not reducing the file size. A B&W 200 dpi 8.5x11 standard letter page is over 1MB! From windows it is the right size ~38kB. When scanning from a mac you also get artifacts from the page. Eg. the white page shows up as slightly grey and if the document is double sided, text from the other side is apparent. Seems like another driver issue since the problem is not nearly as bad from windows. Print speed also seems a little disappointing. I don't think I'm approaching 25ppm; seems to be more like 10 but I haven't timed it.
Overall Review: This is a pretty big printer. You wouldn't want it on your desk. If I had to do it again, I'd probably get the brother mfc 9840cdw just because it seems to work better with OS X 10.6. I bought this because of complaints against the 9840 destroying envelopes and being noisy.
