Solid ink technology is a printing technique used in computer printers and multifunction devices. A multifunction device is also known as an “all-in-one” printer that can print, scan, copy, fax, email, and on newer models, there are several other functions as well. Wikipedia offers in depth information on solid ink technology, some of which will be discussed here.

Solid ink technology utilizes solid ink sticks instead of the ink you normally see in printers. The ink sticks melt and then use a process relative to offset printing to get images into paper. Offset printing is where an image is transferred from a plate to a rubber blanket, then to the printing surface.

There are claims that using the solid ink method produces more vibrant colors, is easier to use, can print on several different types of media, and is guaranteed not to smudge or stain. Solid ink technology is also thought to be more environmentally friendly because it reduces the amount of waste, and does not contain ozone.
A number of projects can utilize solid ink technology, including every day printing, but high volume printing is where solid ink use truly excels. The primary use for solid ink is color printing, and is considered a great tool to increase office productivity. Invitations, greeting cards, pictures, and transparencies are just a few of other items in which solid ink printing would be an excellent choice.

As a point of caution, documents printed with sold ink should not be used in conjunction with laser printers. The heat from the laser will cause the wax ink to discolor and possibly damage the laser printer. Currently, Xerox is the only brand of printers that is offering solid ink technology, but several other companies are looking into adding solid ink into their products as well. Cost and upkeep of a solid ink printer is relatively close to that of a laser printer, but standby usage can be higher than normal.
