We have an HP Officejet 6500A. It is an all in one and networkable (is that even a word..lol). Still fairly new, but I like it. I don't know how fast it goes through ink. We will find out soon as I will have to print a bunch of papers for the kids handwritting.
We are getting ready to buy a new one. The hubby researched a lot over the weekend and we chose a canon printer. The ink has a much higher page yield than the others we found. We also have a HP all in one.
