Conclusion: If you have more than one computer and you are looking for a new All-In-One office printer, then I think this one would be great. Because this is not a photo printer I won’t complain that the photos were not very good, but I will say that I was disappointed in the speed of the document printing. As I mentioned above, the printer would stop printing about every 3 pages, my assumption is so that it could fill up its memory.
Summary: Canon touts the Canon Pixma MX850 as a multifunction powerhouse, and it's worthy of such a description. On top of being fast, easy to use, and excellent at outputting documents and photos, the MX850 includes features such as a duplexer and an automatic document feeder — making it an office-friendly printer. Despite its less-than-impressive scanner output, the Pixma MX850 is a stellar choice.
Summary: This is a multi function unit (as it has fax ) but for me anyway the major selling point is it’s ability to print A4 photo quality borderless images in 68seconds, yes I do mean one minute and eight seconds.
