Chapter 10: Installing and Configuring Printers Flashcards
Printer
Electromechanical output device that is used to put information from the computer onto paper.
Four classifications of printers
Impact
Inkjet (Bubble-jet)
Laser
Thermal
The most basic type (classification) of printers
Impact
How do impact printers operate to get ink onto paper?
These printers use a form of impact on an inked ribbon to make an imprint on paper – like a typewriter.
Paper Feed machanism for an impact printer
Tractor Feed
What type of printer, and specifically what part of that printer, requires this paper?
The tractor feed of an impact printer
Two major types of impact printers
Daisy Wheel
Dot Matrix
Daisy-Wheel Printers
One of the oldest printing technologies in use.
Contains a wheel that looks like a daisy, with raised letters & symbols on each petal.
A hammer strikes the back of the desired petal against a print ribbon, over paper, producing the letter.
Printhead
The component of a daisy-wheel printer that houses the daisy wheel.
Solenoid
The component of a daisy-wheel printer that acts as a hammer, striking the back of the “petal” on the daisy wheel that corresponds with the desired letter to be printed.
The speed of a daisy-wheel printer is measured in _____
Characters per second (CPS)
What are the two largest disadvantages of the daisy-wheel printer?
Poor speed
Loud
What are the advantages of a daisy wheel printer?
It’s an impact printer, which means you can use it to print multipart forms (duplex forms, etc – impact paper).
It’s relatively inexpensive, compared to laser printers
Print quality is comparable to a typewriter.
Name the parts of a daisy-wheel printer
What is the difference between a daisy-wheel printer and a dot-matrix
A dot-matrix printer doesn’t have a daisy-wheel with characters on it. Instead, it has a print head with a row of pints that are triggered in patters to hit the paper, forming letters.
What is the disadvantage of a dot matrix printer?
The print quality is worse than the daisy-wheel.
Refered to as ‘draft quality’
Early models only used 9 pins, creating a fuzzy look for letters printed.
NLQ
Near Letter Quality
A level of quality produced by a dot-matrix printer that almost lives up to the quality produced by a typewriter.
Dot-matrix printers eventually got to this point.
What distinguishes impact printers from inkjet printers?
Inkjet printers spray ink on the page in the form of images, whereas impact printers impress a specific image by striking the page.
The primary parts of an inkjet / bubble-jet printer
Print head / ink cartridge
Head carriage, belt, and stepper motor
Paper-feed machanism
Control, interface, and power circuitry
Inkjet / Bubblejet’s Print Head
Contains many small nozzles (100-200) that spray the ink in small droplets onto the page.
Sometimes this is part of the ink cartridge itself.
CMYK
Cyan, Magenta, Yellow and Black
Main ink jets on an inkjet / bubble-jet printer
Inkjet / Bubble-jet Maintenence Station
Where the print head sits while not printing.
Includes a small sunction pump and ink-absorbing pad.
Station pulls ink through the print head’s nozzles using vacuum
Print Head Carriage
Component of the bubble-jet / ink jet printer that moves back and forth during printing.
Contains a physical portion of the print head
Sometimes contains an ink reservoir
Name this part of an inkjet / bubble-jet printer
Print Head Carriage
Stepper Motor
A component of inkjet / bubble-jet printers that moves the print head carraige.
Named this way because it moves the same, pricese distance each time it’s activated, allowing the carriage to get to specific parts of the page.
A stepper motor is also known as
carriage motor
carriage stepper motor
