Слайды и текст этой презентации
Слайд 3 Major descriptions of printers it is been: -width
of carriage of printer -speeds of printing -discriminability of printer
Слайд 4 On the method of receipt of image on
a paper, printers are the method of causing of
dyeing material :
-matrix
- stream
-laser
-light-emitting- diode
- thermal
Слайд 5 Matrix printer. computer printer, creating an image on
a paper from separate little points by a shock
method. Matrix printers - the eldest from the printers applied
to this day. Their mechanism was invented in 1964 by a corporation
Слайд 6
Stream printer
On principle of action ink-jet printers differ
from matrix unstressed office hours due to that their
plotting head is a set of not needles, and thin
nozzles the diameters of that make the tenths of millimeter. The first firm making an ink-jet printer is "Hewlett-Packard". The era of domestic printers was begun with 1985
Слайд 7
Laser printer
Laser printers have more vast possibilities as
compared to any other types of printers. They differ
in high-rate enough of printing, but cost expensive.
Слайд 8
Light-emitting-diode printer
one of types of printers, showing by
itself the parallel branch of development of technology of
the laser printing. Light-emitting-diode technology of printing was invented by
a firm Casio. The first light-emitting-diode printer was produced in a sale by a company OKI in 1987, and in 1988 by the same company the first cultured light-emitting-diode printer was produced.Слайд 10 On a matrix printer even today subzero enough
discriminability and he is not quite intended for adequate
work to the photo and other high-quality images.
Thermal printer
Слайд 11 scanner - a device analyzing that some object
(an image, text, is ordinary) creates the digital copy
of image of object.
Слайд 12 In 1857 the Florentine abbot Giovanni Caselli invented
a device for an image transfer on distance
Слайд 13 principle of action. The scanned object is laid
on glass of plane-table by the scanned surface downward.
Under glass a movable lamp motion of that is regulated
by a foot-pace engine is situated. principle of action. The scanned object is laid on glass of plane-table by the scanned surface downward. Under glass a movable lamp motion of that is regulated by a foot-pace engine is situated.Слайд 16 Hand scanner subzero permission, small speed of work,
narrow stripe of scan-out, the defects of image are
possible, as to the user will difficult move a scanner
with permanent speedСлайд 17 the sheet of paper is inserted in a
crack and stretched out on directing rollers into a
scanner by a lamp.
Слайд 18 book scanner allow considerably to promote safety of
documents in archives, due to the very delicate handling
originals.
Слайд 19 planetary scanner are used for the scan-out of
books or easily damaged documents. At a scan-out there
is not a contact with the scanned object
Слайд 21 In order that to do work with documents
