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.
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.
(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 .
Sublimation printers are professional devices widely used in demanding graphic arts and
photographic applications for printing on mugs, license plates and other
popular hard surface items. 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.
(Designjet) 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.
A copier (also known as a copy machine) is a machine that makes paper copies
of documents and other visual images quickly and cheaply. Most current
photocopiers use a technology called xerography, a dry process using heat.
Copiers can also use other technologies such as ink jet, but xerography is
standard for office copying.
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.
Anyone who has for use more than one computer has good reason to
consider sharing a printer over a network. No matter what kind of environment
you work in , you can save both space and money when you share over a network.
And you can use that extra cash to buy a printer that better suits your needs.
Wireless printer allows to work with wireless network, and take
advantage of these benefits: print from anywhere in your home or office,
say goodbye to cord clutter and the length of printer cables determining the
placement of other peripherals, share a single printer with an entire
household or office, save on the hardware and energy costs.

POS receipt and banking
printers these printers realize innovative technology and
functionality to increase productivity, and reduce costs. A
receipt printer plays an integral role in
any POS (Point-of-Sale) system,
signaling the cash drawer to open when the transaction is completed.
ID Card Printer. The Magicard is a high-value

programs in need of an on-demand
Most Magicard printers provide extra card security with the inclusion of a
secure holographic watermark system called HoloKote. HoloKote gives you the
option of adding a secure watermark across the surface of each printed card at
no extra cost. The HoloKote watermark can be applied during the normal
printing process. With this printer, you can choose from four fixed HoloKote
patterns (waves, rings, keys, and globes) selectable from the printer driver.
The printer also accepts Magicard HoloPatch card stock. HoloPatch cards
highlight a portion of the HoloKote watermark to create a high visibility
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. There are multi-purpose printers , that
can print different types of labels. For example, label printers used in
supermarkets can print bar codes as well as normal text. There are also some
label printers that can print different sizes of labels on goods.
