He said that the method wasn't useful for printing just a few sheets of text, but for a hundreds of sheets the method was fast and economical” (Wu7). I believe this is very interesting because it gives you an insight on where printers originate from and how simple they

The printing press was an interesting and world changing machine that was used for the mass production of written works for distribution. Such a revolutionary process actually worked through an easy process that included only a few steps. First, every letter had to have been carved into a steel object known as a punch. These punches were eventually hammered into a piece of copper otherwise known as a blank. The blank was used as a mold for a mixture of molten alloys created by Gutenberg who was once a stonecutter and a goldsmith; the mixture consisted of lead, antimony and bismuth. This mixture of metals created an alloy that was easily cooled and handled, but strong enough not to wear down over repeated use. In their creation, the base sizes for the letters had to be determined and marked out ahead of time. Wider letters had wider basis, such as the difference between a capital z and a lower case l. The blocks

a. You input information perhaps via a keyboard or mouse to the computer and you receive output via a monitor or printer or some such device

Single prints, photo books, greeting cards, calendars, and posters are some of the available print options

Q: Which printer type creates a digital image by propelling droplets of ink onto paper?

This output hardware sends information in the form of images, sound, or various other tangible imagery usually, to some form of input hardware on another system. It is not designed to receive data only to send. The most familiar of these devices is the visual display or computer monitor. These monitors are usually synonymous with a computer and every system is equipped with or able to connect to a Visual Display Unit. Projectors, audio systems, printers, and faxes are all examples of output hardware.

• Letter - A formal form of communication and record consisting of a standard structured format and should include the senders details and address, the recipients address, the date written, any reference details e.g. order number etc finally ending with a signature.

The earliest printing in China was the block printing method in the first Century B.C., where the individual sheets of paper were pressed against wooden blocks that had text and illustrations carved into them. This process could print hundreds and even thousands of copies, this technology played a significant role in promoting the spread of culture. A block carver named Bi Sheng made movable types with clay during the period from1004 to 1048. This method each type was carved with one character and the types could be set independently according to contents of different articles. After printing, the movable types could be reused and this improved technology is called movable-type printing. (LAN, 2008)

A printer is an output device because data from the computer is being printed out meaning data is going out of the computer, instead of it going in.

d. Print Options offers different settings that allow the user to change how documents prints.

Each block was its own letter or character and it was very inefficient. This method of printing is known as movable type. This technique was used in Asia hundreds of years before Gutenberg. Gutenberg used a casting and metal alloy system to make movable type much more efficient.

In addition to the regular cartridges, it also uses Imagine cartridges, which contain not only die cut shapes, but also patterns for making your own scrapbook papers. The machine uses HP printer cartridges and can print 1200 dots per inch.

Gutenberg knew the difficulty of printing with carved wooden whole pages and in 1450 he devised a more rational way of printing, based on movable type.

The concept of inkjet printing originated in the 20th century, and the technology was first extensively developed in the early 1950s. Starting in the late 1970s inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, Hewlett-Packard (HP), and Canon. Although inkjet printers only appeared on the consumer market in the late 1980s, they had been under development for more than twenty years by that time. In the mid-1970s, printer companies realized the potential of the technology that would make dot matrix printers obsolete. The challenge, however, was to come up with a way to create an affordable inkjet printer that would reliably create high-quality print outs .In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Epson, and Lexmark, a 1991 spin-off from IBM.[1]( "IBM Archives: 1990s". 03.ibm.com.

NC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders. The CNC in CNC Machining stands for Computer Numerical Control. On the surface, it may look like a normal PC controls the machines, but the computer's unique software and control console are what really sets the system apart for use in CNC machining. Under CNC Machining, machine tools function through numerical control. A computer program is customized for an object and the machines are programmed with CNC machining language (called G-code) that essentially controls all features like feed rate, coordination, location
