Summary: All functions of this all in one unit perform extremely well but by far the greatest feature of all lies in replacement ink cartridges. As you know, individual replacement ink cartridges typically sell for upwards of $15 each. This particular model can use Brother LC-75 high capacity cartridges. Amazon sells 24 packs of these generic cartridges for an astounding $15, more or less. I have used these cartridges without noticeable change in print quality.
