Printer

The purpose of configuring printer availability on the advance tab of the printer properties dialog box is to

configure the days and times a printer is available

impact printer

continuous form paper arranged into a roll or folded stack.

dots per inch

dpi

thermal transfer printing

technology uses ribbon printer cartridges containing waxy ink

Dot Matrix

use a platen rubberized roller to hold the paper in place and to advance the paper . The paper is advanced one line at a time while the print head moves horizontally back and forth across the paper. Pins in the print head strike the ribbon as it moves across the paper which eventually forms letter and characters. The main advantage of doy matrix printers is that they can be used to print multipart forms (Impact paper ) Forms letter and characters

Inkjet printers

use ink-dispersion and wet ink to transfer an image onto paper.

thermal printer

uses a heating element to create the image on the paper.

solid ink printer

uses solid blocks of waxy pigment which are melted and dispersed onto paper.

Impact printers

work by banging a print head or needle against an ink ribbon to make a mark on the paper, very similar to an old typewriter. There are three types of impact printers:

Thermal Printer

works by using heat to create images on paper.

Multifunction

An all-in-one printer which contains additional technologies such as scanner, fax, and copier

Processing

Memory Print hobs are stored in the memory on the laser printer. Builds the entire page in memory.

Transferring

Pickup rollers grab a single sheet of paper from the paper tray or manual feed slot and move it into the printer. A separator pad (commonly two or three inches wide) placed in the middle of the paper path keeps the pick up to one paper at a time. Once the paper moves into the printer, it receives a positive charge as it passes through the secondary corona wire or transfer roller. The negatively charged toner is attracted to the positively charged paper and transfers from the drum to the paper.

Dot matrix

Printers often use continuous feed paper with pinholes on each side of the paper. The pin holes are palced on tractor feeds, Which advance the paper through the priter Allows fast rpining and reduced jams

Line

Prints an entire line at once, allowing faster output. Depending on the type, an impact line printer might use a wide comb to produce dot matrix output, or it might have character glyphs arranged on a drum, chain, or b

Fusing

The paper passes through a set of rollers that apply heat and uniform pressure to the paper and toner, curing the image onto the paper. As the paper passes by a static eliminator strip, it neutralizes any remaining electrical charges on the paper. This prevents the paper from jamming in other areas of the printer.

Inkjet

: The printer which uses ink-dispersion and wet ink to transfer an image onto paper

Cleaning

A physical and electrical process cleans the previous image off the photosensitive drum.Excess toner is scraped off the drum by a rubber cleaning blade into a debris cavity called a hopper. Some printers use a wire with AC voltage to remove the charge from the drum surface, which allows the excess toner to drop off the drum into the hopper.Lubrication is applied to the heat roller to ensure an even transfer of the next image.

Cleaning

A physical and electrical process wipes the previous image off the photosensitive drum.

Virtual

A piece of software which sends output to a file, a software application, or a device other than a printer

The direct thermal printing technology

requires a heat-sensitive paper.

Dot matrix

Prints one character at a time using a print head made up of small pins. The pins are individually struck against the ribbon to create a pattern of dots which can form characters or pictures. Dot matrix printing is faster and more flexible than daisy wheel printing, but it produces lower quality text. Print heads typically have between 9 and 24 pins. Higher pin counts create sharper output.

Cleaning

Remove excess toner

Problem: Misaligned inkjet print heads

Resolution :Use the printer's software to calibrate the print heads. Toner is depletedReplace the toner cartridge

Problem: Clogged inkjet print heads

Resolution Use the printer's software to clean the print heads.

Problem: Toner is low.

Resolution: Remove the toner cartridge, shake it from side to side, then reinsert it.

Problem:Toner is depleted

Resolution: Replace the toner cartridge

Multifunction printer

Scanner fax and copier

Printer problem: Laser excess toner reservoir is full.

Solution:Slide the small plastic strip back and forth on the toner cartridge

Developing

The drum passes by a developing roller covered in toner. The toner is a negatively-charged combination of plastic and metal particles. Areas of the drum where the laser hits lose their electrical charge, this attracts the negatively charged toner from the control blade of the roller. Areas on the drum that still have a negative charge repel the toner. This creates a mirror image of what is to be printed in toner on the drum.

Developing

The drum passes by an evolving roller covered in toner.

Exposing

The laser projects the image on the photosensitive drum.

Exposing

The laser projects the image on the photosensitive drum. Where the light hits the drum, the negative charge is dissipated to the grounded center of the drum. This results in areas with a lower negative charge than the rest of the drum. These areas create an electrical image of the print data on the surface of the drum.

Fusing

The paper passes through rollers that apply heat and uniform pressure to the paper and toner, curing the image onto the paper.

Transferring

The pickup rollers grab a single sheet of paper from the paper tray and move it into the printer.

Charging

The primary corona wire applies a negative charge to the photosensitive drum as the surface of the drum rolls across the surface of the conditioning roller. This removes any electrical charges that might remain from the previous print image.

Charging

The primary corona wire applies a negative electric matter to the photosensitive drum

3D

The printer which uses an automated process to add source material to an object, building it from the ground up

Impact

The printer which works by banging a print head or needle against an ink ribbon to make a mark on the paper

Which components are normally found in these printers

Toner Ribbons and tractor feeds

daisy-wheel printer

Uses a wheel-shaped printing mechanism containing predefined character glyphs arranged like petals on a flower. Much like a mechanical typewriter, a mechanism moves the wheel across the paper and a hammer strikes one petal against the ink ribbon, leaving an imprint of the character on the printer. Daisy wheel printers can produce high-quality text output, but they're slow and are limited to the specific glyphs (typically 96) on the wheel. To even change the font or text size, you must change the wheel.
