I have had the HP Officejet Pro 8600 since Oct 2013 and have been more than satisfied with it. I use it wireless which keeps one wire of my desk top. I am impressed with the quality of the colored photos, and documents.
Up until about 4 years ago, I volunteered my time writing memoirs for Hospice patients and printed two 8-1/2 x 11 books for each patient. There would be a lot of photos, some new, some old, and they always came out good. The families were always surprised by the quality of the finished copies I gave them.
I tried a competitive printer one time and couldn't wait to get rid of it. I couldn't count on getting quality color uniformly from one copy to another. I was unable to get good mileage from each ink cartridge.
