Printing with solid ink?

Although this particular technology was first brought to life in 1986 and marketed in 1991, it is still uncommon for residential uses. Yet, this technology generates up to 90% less waste than their laser counterparts, in addition to being much more economical. That is due to fact that solid ink printers do not use bulky cartridges, fusers, or imaging units. Resulting in a significant decrease of the elements that eventually need to be changed. Furthermore, they are quite practical, as they do not leak, do not stain, and are made from a non-toxic, resin-based polymer.
