The pins which are arranged vertically are used to print by striking against the ribbon just like a typewriter
on a platen paper. Across the page the print head will move sideways so that by sequential types on the right pins a desired character
will be formed. Dot matrix printers can print right to left or vice versa. The effect of dot matrix printer is rather similar to a
digital clock and its segments.
The time came when changing ribbons became a struggle for people in need of the service of printers. It was in 1984 when the first
inkjet printer was introduced in the market. The inkjet printer came with ink printer cartridges which were very convenient for everyone
and colors are much easier to change, since then these types became fairly common. From the matrix of the inkjet printer, prints are
formed at the speed of one line at a time. Inkjet printers are capable of producing high quality printed graphics. But the downsides
of these printers are high maintenance cost for ink cartridge replacements and the dependence of its continuous use to the environment.
Nevertheless, the vast majority of today’s consumers are in choice of inkjet printer technology.
The birth of laser printers grew and became widely used in the 80’s. This type of printer allows texts and graphics to be printed
one page at a time in high quality standard. With laser printer, a complete page image is transferred to a photosensitive band or drums
and from a laser beamed buffer data is scanned as the band or drum turns. By using separate sets of toners and drums color is made possible
as well as availability of different sizes of paper.
Color laser printers are type of laser printers that add colored toner especially in printed graphics in three additional passes or steps.
The order of the colored toner is cyan, magenta, yellow and key color which is the color black. It is also known for it’s acronym as
CMYK and often referred to as the “four color” or the “process color”. CMYK which is subtractive color model that
is used to describe the process of printing that is especially used in color printing. There are types of color laser printers that use a
large belt that is capable of accommodating a full sheet of paper to generate colored printed images. Among other types of printers, color
laser printers are the finest in terms of speed and quality of its printed text and images, but unlike inkjet printers, are way too expensive
to common public consumers.
