The HP Deskjet 3930 is a fairly good machine. Compared to the other printers I have owned, it jams considerably less often, but it does seem to use up the ink about as fast as I can purchase it. However when it is not out of ink, the pictures it prints are topnotch compared to most other printers' attempts I have sampled.
There is a panel in the back of the machine for easy removal of jammed paper, which is a big relief. When jamming occurs, you simply open the panel at the back, remove the paper, and click the button on the screen that says "continue printing". Owning this printer has made my work so much simpler. If I ever have to buy another printer, I will look for a Hewlett-Packard first. Altogether, the Deskjet 3930 is a handy office supply to have at home or at work.
Update On Oct 13, 2009: It is also very economical. After searching for a new printer for my 2nd computer, I realized I need to listen to my own advice and stick to Hewlett-Packard. I think my wallet would be very greatful.
