I needed an inexpensive inkjet printer for a new computer with Windows 7 (my older printer was not compatible with the new software), and after looking around bought the HP Deskjet D2680 for its value proposition. I have always had HP printers (though I typically buy higher end printers), and have had quite good luck with them from a performance and reliability standpoint. So far the D2680 seems to be largely living up to the reputation of its predecessors.
The printer is extremely basic, and installation (especially with Windows 7) is a total nonevent. Print quality is decent: I mostly use it for black and white printed drafts. For that it's fine, and the pages are highly readable in every typeface and font size I have used (PDF files of various sorts also look great). For color photo printing the D2680 is outclassed by many other machines. If that's your primary use, I think there are better choices available.
Ink use is moderate, and I recommend the larger capacity ink cartridges for optimum cost and convenience. I have had no printing issues with this printer, but I have had one small mechanical issue with it: on one occasion the power button became physically jammed in the "on" position, as it sits in a relatively deep plastic well. I was able to dislodge it with a bit of effort, but that is clearly not the best design concept for a heavily used switch. I considered downgrading my review to three stars because of the switch issue, but since it has been used many times since without reoccurring, I think the D2680 deserves four stars for good all-around performance at a stellar price.
