Multi-functional Devices (MFD)
Multi functioning devices are electronic devices used in everyday life which can perform multiple
tasks.
Printers
1. The Photocopier. First electro-photography photocopier in a process called Xerography (say
it as zerography)
2. Dot Matrix Printer. Introduced in 1957 it prints dots in a pattern to create an image.
3. Thermal Printers. Popular in 70s and 80s, it adds and image to thermochromics paper. The
chemical may have been toxic
4. Laser Printer. High quality printing, laser printing uses a chemical called toner that
electrically charges powered ink.
5. Ink jet printers. Developed in the 70s, uses droplets of ink to recreate the digital image. Ink
can be expensive to replace and you have to wait for ink to dry.
Multi functioning Printers
They can:
o Print
o Copy
o Email
o Fax
o Scanning
o Connect to the Wi-Fi
It contains:
o USB ports
o Wireless capabilities
o Memory(to store information
o Print trays containing paper
o Touch screen to input information
o One or more processors
o Mechanisms for printing
Printers require software just like computers do. Printers have applications working on it just like
computers as well.
Environmental impacts
Toxic chemicals getting into water systems and toxic for the environment
Deforestation
o We are becoming a paperless society but is still required
o We still use printers for physical photos instead of electronic ones
Wastage in throwing way plastics
3D Printing
In a process called “additive manufacturing” It’s now possible to print objects. You could sell the
blueprint of an object the print it in your home, you will not have to worry about transport.
You can 3D print objects in space, which would cross out the requirement to send equipment into
space.
