You want a laser printer if you're not printing photos. Laser "cartridges" are called toner and don't dry out like inkjet cartridges do. You can go for months without printing anything and it will still work.
I have the Brother 2280 model (bought a refurb one at Staples a couple of years ago for about $80) and it's awesome! I'm still on the toner it came with. I opted for the black & white printer because I just print documents and coupons. They make color laser printers as well. Look around for the 2280 model...you can regularly find it for about $100. Slickdeals posts sales on them a lot. It does duplex printing, copy, scan, etc. It can be hooked up wirelessly to print from your iPad or whatever also. It's been a huge moneysaver for us! I was sick of buying inkjet ink and having it dry out after only one or two uses.
