1
Q

Printer that creates an image on paper by physically striking an ink ribbon against the paper’s surface. Tend to be slow and noisy but when speed, flexibility, and print quality are not critical, they provide acceptable results

Q

An aluminum cylinder coated with particles of photosensitive compounds. Drum is grounded to the power supply, but the coating is not. When light hits these particles, whatever electrical charge they may have “drains” out throughout the grounded cylinder

21
Q

Exposes the entire surface of the imaging drum to light, making the photosensitive coating conductive

A

Erase Lamp

22
Q

Located close to the photosensitive drum, never touches the drum. When it is charged with an extremely high voltage, an electrical (corona) forms, enabling voltage to pass to the drum and charge the photosensitive particles on its surface. The primary grid regulates the transfer of voltage, ensuring that the surface of the drum receives a uniform negative voltage of between 600 and 1000 volts

A

Primary Corona Wire/Charge Roller

23
Q

The writing mechanism of the printer. Writes a positive image to the drum

A

Laser

24
Q

In a laser printer, is a fine powder made up of plastic particles bonded to pigment particles. Particles of it are attracted to the areas of the photosensitive drum that have been hit by the laser

A

Toner

25
Q

In older printers, a thin wire applies positive charge to the paper, drawing the negatively charged toner particles to the paper

A

Transfer Corona

26
Q

In newer printers, accomplishes the same feat as transfer corona that draws the the toner onto the paper. The paper, with its positive charge, is also attracted to the negatively charged drum

A

Transfer Roller

27
Q

Removes the charge from the paper preventing it from wrapping around the drum

A

Static Charge Eliminator

28
Q

Most are located outside the toner cartridge, especially in large, commercial-grade machines. Prone to a build-up of dirt, toner, and debris through electrostatic attraction, and it must be cleaned. Quite fragile - usually finer than a human hair

A

Transfer Corona/Roller

29
Q

Almost always separate from the toner cartridge. Usually close to the bottom of the toner cartridge and has two rollers to fuse the toner

A

Fuser Assembly

30
Q

Uses friction to separate a single sheet from any others that were picked up

A

Separation Pad

31
Q

Reverses the paper allowing for printing on both sides

A

Duplexing Assembly

32
Q

Printer that uses melted material to create prints of 3D objects. Most commonly uses plastic filament on spools. Also need manual connection of the plastic filament(s) to the print device

A

3D Printer

33
Q

Program that converts the output from your computer into a specific format and saves the result to a portable file that looks like the printed page would have

A

Virtual Printer

34
Q

Contains a variety of control codes for transferring data, some of which can be used to control printers

A

American Standard Code for Information Interchange (ASCII)

35
Q

Page description language developed by Adobe Systems as a device-independent printer language capable of high-resolution graphics and scalable fonts. Because it is understood by printers and not the computer’s CPU so they print faster. Sees a page as a single raster image

A

PostScript

36
Q

Features a set of printer commands greatly expanded from ASCII. Designed with text-based output in mind; doesn’t support advanced graphical functions. Not a true page description language; uses a series of commands to define the characters on the page

A

HP Printed Command Language (PCL)

37
Q

Windows uses this component of the OS to handle print functions. Uses the CPU rather than the printer to process a print job and then sends the completed job to the printer

A

Graphical Device Interface (GDI)

38
Q

Print path introduced by Windows Vista a new printing subsystem. Provide several improvements over GDI, including enhanced color management and better print layout fidelity

A

XML Paper Specifications (XPS)

39
Q

Most common variety of scanner. Place a photo or other object face down on the glass/platen, close the lid, and then use software to initiate the scan. The scanner runs a bright light along the length of the platen once or more to capture the image

A

Flatbed Scanners

40
Q

The resolution a scanner achieves mechanically

A

Optical Resolution

41
Q

Define the number of bits of information the scanner can use to describe each individual pixel. Determines color, shade, hue, and so forth. 24-bit and 48-bit common

A

Color Depth

42
Q

A number that defines how many shades of gray the scanner can save per pixel. 8-bit, 12-bit, and 16-bit common

A

Grayscale Depth

43
Q

Used by a multifunction device to grab pages to copy, scan, or fax. It is typically on top of a multifunction device and you place a stack of pages in the tray

A

Automatic Document Feeder (ADF)

44
Q

Standalone network device that connects a printer to the network but may not be able to use all of the features of the multifunction device

A

Print Server

45
Q

Print server in a router

A

Integrated Print Server

46
Q

Enables you to queue up multiple print jobs that the printer will handle sequentially

A

Print Spooler

47
Q

A pattern of dots

A

Raster Image

48
Q

A chip that laser printers use to translate the raster image into commands to the laser. Needs RAM to store the data that it must process

A

Raster Image Processor (RIP)

49
Q

Enables the printer to insert smaller dots among the characters, smoothing out the jagged curves that are typical of printers that don’t use it. Requires RAM

A

Resolution Enhancement Technology (RET)

50
Q

Using a substitute printer driver for a printer, as opposed to using one made exclusively for that printer

A

Printer Emulation

51
Q

Uses hardware to generate an International Color Consortium (ICC) color profile, a file that defines the color characteristics of a hardware device

A

Color Calibration
