Speed & Quality
Images Per Minute (IPM): In March 2009, the International Standards Organization implemented a print standard for inkjet printer document print speeds which is a universal measure utilizing three types of standardized test documents in "real world" conditions - one, four page Excel document, one - four page Word document and one-four page PDF document. This new standard will allow you to easily compare the print speeds of printers manufactured by different companies.

Don't Even Think About This One
I've had this printer for over 2 years. In that time I have come to loath it.
It will not hold the WiFi connection with any regularity and will not print from the USB cable.
I would NOT BUY THIS PRINTER AGAIN IF THEY GAVE IT TO ME!!!

Wastes Ink
While this printer has excellent functionality, it is incapable of printing in pure black and white (i.e. using ONLY the black cartridge). Using color for more intricate greyscale is fine, but I most often do not need this detail and find that constantly buying colored ink that I thought I was conserving is highly frustrating. Additionally, the printer does some kind of maintenance after most every print run, which-in my opinion-is unnecessary and overly time consuming, especially when wanting to print more than one document in succession.

Great until issues - Second machine...
I have purchased two of these machines because of the beautiful prints and ease of use. The second one has now broken as well with a different issue and I am very dissapointed.
