Printer-
Printers are one of the most popular computer peripherals and are commonly used to print text and photos. In this era, the technology of printers changes day by day.
This story is about the printer.
How does a printer work?
A number of bytes of data streams into the printer from our PC or laptop. An electronic circuit in the printer understands how to print this data so it looks directly on the page.
The electronic circuit in the printer induces the crown wire. This is a high-voltage wire that gives a static electric charge to anything close by.
The crown wire stimulates the photoreceptor drum so the drum builds a positive charge spread reliably over its surface.
At the same time, the circuit impels the laser to make it draw the image of the page onto the drum. The laser column doesn't generally move: it sways off a moving mirror that looks at it over the drum. Where the laser shaft hits the drum, it erases the positive charge that was there and makes a region of negative charge. Constantly, an image of the entire page creates on the drum: where the page should be white, there are districts with a positive charge; where the page should be dull, there are regions of negative charge.
An ink roller reaching the photoreceptor drum covers it with infinitesimal particles of powdered ink (toner). The toner has been given a positive electrical charge, so it holds fast to the bits of the photoreceptor drum that have a negative charge (a review that backwards electrical charges pull in likewise that opposite posts of a magnet attracting). No ink is pulled in to the bits of the drum that have a positive charge. An inked image of the page creates on the drum.
A bit of paper from a holder on the contrary side of the printer deals with up toward the drum. As it moves along, the paper is given a strong negative electrical charge by another crown wire.
Right when the paper moves near the drum, its negative charge attracts the earnestly charged toner particles from the drum. The image is moved from the drum onto the paper be that as it may, for the event, the toner particles are basically laying gently on the paper's surface.The inked paper experiences two hot rollers. The glow and weight from the rollers consolidate the toner particles forever into the strands of the paper.

The printout lifts out of the side of the copier. On account of the fuser unit, the paper is still warm.
How laser printer works?
A laser printer utilizes a light emission for printing. This light of the laser changes the electrical charge on the drum, any place it hits on the grounds that as the paper goes through the printer, the laser shaft strikes at the outside of the drum and this is known as a photoreceptor. By changing the charge on the drum, the laser shaft can print designs onto the photoreceptor. When the structure made on the drum, it covered with toner from a toner cartridge. In the greater part of the cartridges, the toner is dark, however, the laser printers are similarly coloured.

Laser printers work by setting out a variety of minuscule, equally separated spots of "ink" on the paper. The dots are so little, and they mix so consistently that content looks practically as perfect as what you get from a conventional typesetting machine. Truly, there are little-barbed edges along bent lines, however, they're difficult to see. Illustrations now and again don't turn out very as sharp, yet they despise everything are splendid enough for an expert look much of the time.
