Here is the information about different types of printers you should be aware of. The main categories are: - laser printers, ink-jets, dot-matrix, multifunctional, etc. Normally home computer users will use ink-jets as they are relatively cheap but superior in quality to dot-matrix. Laser jets and other printers created by new technology are more expensive and more commonly found in the offices.
spray ionized tiny drops of ink onto a page to create an image. This is achieved by using magnetized plates which direct the ink's path onto the paper in the desired pattern. Almost all ink-jets offer a color option as standard, in varying degrees of resolution. Ink-jet printers are capable of producing high quality print which almost matches the quality of a laser printer. A standard ink-jet printer has a resolution of 300 dots per inch, although newer models have improved on that. As a rule color link-jet printers can also be used as a regular black and white printer.
Laser printers
operate by shining a laser beam to produce an image on a drum. The drum is then rolled through a
pool, or reservoir, or toner, and the electrically charged portions of the
drum pick up ink. Finally, using a combination of heat and pressure, the ink
on the drum is transferred onto the page. Laser printers print very
fast, and the supply cartridges work a long time. Color laser printers use the same toner-based printing
process as black and white ( B/W) laser printers, except that they combine four
different toner colors. Color laser printers can
also be used as a regular black and white laser printer.
LED/LCD printers are types of electro photographic printers that are identical to laser
printers in most ways. Both LCD (liquid crystal display) and LED (light-emitting diode) printers
use a light source instead of a laser to create an image on a drum. In most contexts, "laser
printer" covers LCD and LED printers as well. The print process is almost identical, but LED
printers use Light Emitting Diodes to charge the drum, and the other uses Liquid Crystals. These
printers produce a very high quality text and graphics print out.
Impact
(Dot-matrix) printers use a set of closely spaced pins and a ribbon to print letters or other
characters on a page. These printers actually impact the page to
print a character, much like a typewriter. Dot-matrix printers vary in terms of speed
and the number of pins they
have. They can run at a speed anywhere between 50 and 500 CPS (Characters Per
Second). The number of pins, which can vary between 9 to 24, determines the
quality of the print job. Dot matrix printers are commonly used for printing invoices, purchase
orders, shipping forms, labels, and other multi-part forms. Dot matrix
printers can print through multi-part forms in a single pass, allowing them to
produce more pages than even high-speed laser printers.
Solid Ink printers
are page printers that use solid wax ink sticks in a "phase-change" process. They work by liquefying wax ink
sticks into reservoirs, and then squirting the ink onto a transfer drum, from
where it is cold-fused onto the paper in a single pass. Solid-ink printers offer better
color consistency than do most technologies, with little variation
caused by changes in temperature, humidity, or type of paper. Solid ink machines
have better reliability, because they have fewer components in comparison, for example with
color laser printers .
Dye
Sublimation printers are professional devices widely used in demanding graphic arts and
photographic applications. True these printers work by
heating the ink so that it turns from a solid into a gas. The heating element
can be set to different temperatures, thus controlling the amount of ink laid
down in one spot. In practice, this means that color is applied as a
continuous tone, rather than in dots, as with an inkjet. One color is laid over the
whole of one sheet at a time, starting with yellow and ending with black. The
ink is on large rolls of film which contain sheets of each color, so for an
A4 print it will have an A4-size sheet of yellow, followed by a sheet of cyan,
and so on. Dye sublimation requires particularly expensive special paper, as
the dyes are designed to diffuse into the paper surface, mixing to create
precise color shades.
Portable printers are usually fairly lightweight and sometimes carry the
option of using a battery instead of drawing power from the computer. Usually
they realize basic print resolutions suitable for plain text
printing. You can find on the market the following types of the portable printers: Thermal printer,
Thermal transfer printer and
Ink-Jet printer. The main advantage of thermal and thermal transfer printers is that they
can be very small. The smallest thermal and thermal transfer printers weigh
approximately one pound. Usually the ink-jet portable printer weighs more than 2 pounds.
Thermal printers require a special type of paper.
Plotters are large-scale printers that are very accurate at reproducing
line drawings. They are commonly used for technical drawings such as
engineering drawings or architectural blueprints. The two basic types of
plotters are called flatbed plotters and drum plotters. Flatbed plotters are horizontally aligned with a flat surface to
which a piece of paper is attached. The paper remains stationary and the
printer moves pens across the paper to draw the image. Drum plotters,
also called upright plotters, are vertically positioned. They have a drum that
the paper rolls on. Drum plotters usually make more noise and are more compact
than flatbed plotters.
Digital Photo printers
Many middle range printers are now able to print photo quality images. Usually an
option with color printers, specialist photo print heads allow a greater
resolution to be achieved to improve photo image quality. Photo ink jet
printers expand their gamuts by adding additional ink colors, usually light
cyan and light magenta.
Network printer is a printer that provides output capabilities to
all network users.
Multifunction printers:
combine top-quality color ink-jet or laser printing with plain-paper and PC faxing, color copying and
color scanning , telephoning- all in one convenient, space-saving
machine. If you work from home or have a small office a
multifunctional device may be ideal.
The
Bravo AutoPrinter is the worlds first automated CD/DVD printing system
that can truly be called innovative. It combines automatic, robotic-based CD
or DVD printing along with full-color, 2400 dpi disc printing all in one
compact, desktop unit.
Printers
for banking: these printers realize innovative technology and
functionality to increase productivity, and reduce costs.
EZ CD/DVD Printers: provide a low cost way to create professional printed CD-Rs and
DVD-Rs. Instead of writing on the CD or applying labels, you can print directly on
the CD surface! With high speed capabilities, a full color image can be
printed directly on the top surface of your CDs in less than 1 minute.
Label
Printers are the smartest way to print labels one at a time.
The printers allow easy installation. You can get high-quality,
professional results every time.
VersaLaser™
(Universal Laser Systems Inc.) is
peripheral tool, that can transform images or drawings on your computer
screen into real items made out of an amazing variety of materials… wood,
