WHAT IS PRINTER?
External device that communicates with another digital device to print what a user sees on a screen.
Printers use small pixels to transfer an image from the system to another surface.
Ink jet and laser printers are the most commonly used varieties of this device, and are most commonly hooked up to a personal computer.
Printing Presses
XEROX MODEL A
The first photocopier were invented in the 1940s by a man named Chester Carlson
Was a manually operated commercial xerographic printer
Model A difficult to operate and it required an incredible 39 step process to produce one copy
XEROX MODEL 914
1959, the first automatic photocopier was invented, the Xerox Model 914. The 914 could reproduce documents up to 9″ x 14″ – hence the name Model 914. It took this huge machine about 15 seconds to warm up and make its first copy, and then 7 seconds between subsequent copies.
The Model 914 weighed a backbreaking 648 pounds, and its dimensions were 42″ x 46″ x 45″.
This huge machine was only able to manage 7 copies per minute
Elisha Gray (1835-1901), American inventor, born in Barnesville, Ohio invented and patented many electrical devices, including a facsimile transmission system
Speed : transmit data at different rates, from 4800 bps to 28 800 bps
A 9600 bps fax machine typically requires 10 to 20 seconds to transmit one page
Printer type : use a thermal printer that requires special paper that tends to turn yellow or brown after a period
More expensive fax machines have printers that can print on regular bond paper
Autodialing : variety dialing features
Some enable to program the fax to send a document at a future time so that you can take advantage of the lowest telephone rates
