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

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

Before we discuss their differences, let's talk about how they are same. First, these die cutters are considered cartridge-based machines. They use artwork and fonts that are available on cartridges. This means that all the machines, with the exception of the Cricut Mini, can be used without a computer. Simply plug in the cartridge, select your shape and size, and press cut.

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.

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

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)

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.

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

This type of digital file can then be read by a vinyl machine to accurately reproduce the design in a piece of vinyl. Hit print and a vinyl machine sends the instructions of the machine to the vinyl piece stock into the design you created. If you do not have the saved file for later use, or you delete the file after you print the original, you might have to do it again if you do not an extra copy. Professional vinyl sign makers require that any new design be saved so that a computerized vinyl printer can use the image to print a new vinyl decal or lettering. Vinyl lettering is an easy way to advertise.

Therefore, Gutenberg invented a punch and mold system in order to produce the movable type for the masses. Over the next five centuries the punch and mold system was refined, so a type tray contained the letters. In addition, the type tray allowed for easier replacement of broken letters. The following books or pages used the same type, which allowed for faster printing (Bantwal). Johannes Gutenberg’s genius lies within utilizing the current 15th century technology and then inventing the leftover part to complete the movable printing press.

• 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 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.

Environmentally conscious designers know about the letterpress which is the process of printing from an inked raised surface especially when the paper is impressed directly upon the surface. This is a very old process which is still used today.

Digital presses are still used primarily in specialty applications. Paper is the biggest individual manufacturing cost, often amounting to 25 percent of revenues. Printing papers are often coated, and are bought in sheets or rolls from distributors. Some customers provide their own paper, but most is bought for customers, with a modest price markup. Paper prices can vary significantly from year to year.

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
