what type of printer is slower than a laser printer, and also tends to smudge on inexpensive paper
Types of Printers
Printer - A device that prints text or illustrations on paper. There are many different types of printers. In terms of the technology utilized, printers fall into the following categories: Dot matrix: A type of affect printer that produces characters and illustrations by striking pins against an ink ribbon to print closely spaced dots in the advisable shape. Dot-matrix printers are relatively expensive and do non produce high-quality output. However, they can impress to multi-page forms (that is, carbon copies), something light amplification by stimulated emission of radiation and ink-jet printers cannot practise.
Dot-matrix printers vary in 3 important characteristics:
Dot Matrix Printer Manufacturers include Epson, Okidata and Brother
Speed: Given in characters per 2d (cps), the speed can vary from most 50 to over 500 cps. Most dot-matrix printers offer different speeds depending on the quality of impress desired.
Print quality: Adamant by the number of pins (the mechanisms that print the dots), it can vary from 9, 18 or 24 pins. The best dot-matrix printers (24 pins) can produce virtually alphabetic character-quality type, although you can still come across a difference if you expect closely.
Ink: Dot Matrix Printer utilize ribbon for ink In addition to these characteristics, y'all should too consider the noise factor. Compared to laser and ink-jet printers, dot-matrix printers are notorious for making a lot of dissonance. Ink-jet: A blazon of printer that works by spraying ionized ink at a sail of paper. Magnetized plates in the ink'due south path straight the ink onto the paper in the desired shapes. Ink-jet printers are capable of producing high quality impress budgeted that produced by laser printers. A typical ink-jet printer provides a resolution of 600 dots per inch, although some newer models offer higher resolutions.
2 types of Ink Jet Printer Technology Piezo and Thermal Ink Jet
Ink Jet Printer Manufacturers include Canon, Epson, HP and Lexmark
Speed: Given in Pages per Infinitesimal (PPM) the higher the PPM the more pages they can impress. About ink-jet printers offer unlike speeds depending on the quality of print desired.
Print quality: Determined past the DPI Dot Per Inch Example 2440 x 1220 DPI (Vertical and Horizontal DPI) The college the DPI the better in terms of impress quality.
Ink: Ink-Jet Printers use Ink Cartridges (subconscious toll)
In general, the price of ink-jet printers is lower than that of light amplification by stimulated emission of radiation printers. Nevertheless, they are also considerably slower. Some other drawback of ink-jet printers is that they require a special type of ink that is apt to smudge on inexpensive copier newspaper. Because ink-jet printers crave smaller mechanical parts than laser printers, they are especially popular as portable printers. In addition, colour ink-jet printers provide an inexpensive mode to print total-colour documents.
Laser: A type of printer that utilizes a laser beam to produce an image on a drum. The light of the laser alters the electric accuse on the drum wherever it hits. The drum is and then rolled through a reservoir of toner, which is picked up by the charged portions of the drum. Finally, the toner is transferred to the paper through a combination of heat and force per unit area. This is as well the mode copy machines piece of work.
Laser Printer Manufacturers include HP, Lexmark, Xerox
Speed: Given in Pages per Minute (PPM) the higher the PPM the more pages they can print. Most ink-jet printers offering different speeds depending on the quality of print desired.
Print quality: Determined by the DPI Dot Per Inch Instance 4880 ten 2440 DPI (Vertical and Horizontal DPI)

Because an entire folio is transmitted to a drum before the toner is applied, laser printers are sometimes called page printers. In that location are 2 other types of folio printers that autumn under the category of laser printers even though they do non use lasers at all. One uses an array of LEDs to expose the pulsate, and the other uses LCD's. Once the drum is charged, nonetheless, they both operate like a real laser printer.
In improver to the standard monochrome laser printer, which uses a single toner, in that location also exist color laser printers that utilize iv toners to print in full color. Color laser printers tend to exist about 5 to ten times as expensive as their monochrome siblings. Laser printers produce very loftier-quality impress and are capable of printing an almost unlimited variety of fonts. Most light amplification by stimulated emission of radiation printers come with a bones set up of fonts, called internal or resident fonts, merely you tin can add additional fonts in i of two means: Font cartridges: Laser printers accept slots in which you can insert font cartridges, ROM boards on which fonts take been recorded. The reward of font cartridges is that they utilise none of the printer'due south memory. Soft fonts: All laser printers come with a certain amount of RAM memory, and you can usually increment the amount of retentiveness by adding memory boards in the printer'south expansion slots. You can and so re-create fonts from a deejay to the printer'south RAM. This is called downloading fonts. A font that has been downloaded is oftentimes referred to as a soft font, to distinguish it from the hard fonts available on font cartridges. The more RAM a printer has, the more fonts that can be downloaded at one time. In improver to text, laser printers are very skillful at printing graphics. However, yous need pregnant amounts of memory in the printer to impress high-resolution graphics. To impress a full-page graphic at 300 dpi, for example, you demand at to the lowest degree 1 MB (megabyte) of printer RAM. For a 600-dpi graphic, you lot need at to the lowest degree 4 MB RAM. Because laser printers are no bear upon printers, they are much quieter than dot matrix. They are too relatively fast, although non as fast as some dot-matrix printers. The speed of light amplification by stimulated emission of radiation printers ranges from about 4 to 20 pages of text per infinitesimal (ppm). A typical charge per unit of vi ppm is equivalent to nigh twoscore characters per second (cps). Light amplification by stimulated emission of radiation printers are controlled through page description languages (PDL's). In that location are two de facto standards for PDL'due south: PCL: Hewlett-Packard (HP) was i of the pioneers of laser printers and has developed a Printer Control Language (PCL) to control output. There are several versions of PCL, so a printer may be compatible with one only not another. In improver, many printers that claim compatibility cannot have HP font cartridges. PostScript: This is the de facto standard for Apple tree Macintosh printers and for all desktop publishing systems. Most software can impress using either of this PDL's. PostScript tends to be a bit more expensive, but it has some features that PCL lacks and information technology is the standard for desktop publishing. Some printers support both PCL and PostScript.
One of the chief characteristics of laser printers is their resolution -- how many dots per inch (dpi) they lay down. The available resolutions range from 300 dpi at the low end to ane,200 dpi at the high terminate. By comparing, offset press usually prints at 1,200 or 2,400 dpi. Some laser printers achieve higher resolutions with special techniques known generally every bit resolution enhancement.
The half-dozen steps light amplification by stimulated emission of radiation press process
Notation * piece of cake fashion to think this is CARS WILL Drive TO FAST CLEANLY
1. Workout or Charging – To make the pulsate receptive to new images, information technology must exist charged. The EP drum is given a negative charge by the primary corona wire around -600 and -g volts
two. Writing - A laser beam is use to write to the EP pulsate causing dots on the drum to lose some of the negative charge
and get relatively positive charge
three. Developing - A toner is transferred from the toner cylinder to the EP drum by attracting the expanse of the drum that has a
Relative positive charge
4. Transferring - The transfer corona wire puts a highly positive accuse on the newspaper once the newspaper has a positive accuse
the negatively charge toner particle leaps from the pulsate into the paper
5. Fusing - The compression roller and fusing roller press and melts the toner into the paper the fuser gets very hot
six. Cleaning – The Photosensitive drum is cleaned before it tin can accept on a new image Other Types of Printers
Photo Printer – Is a type of printer utilize for press photographs.
Dye-Sublimation Printer – Is a type of printer which employs a printing process that uses heat to transfer dye to a medium such as a plastic card, printer paper or poster paper.
Thermal Printer- Is a type of printer that produces a printed image by selectively heating coated thermo chromic paper, or thermal newspaper equally it is usually known, when the paper passes over the thermal print head. The blanket turns black in the areas where information technology is heated which then produce an epitome.
All-in-One Printer - A printer than tin also do scanning, fax and make copies
Plotter - A big device use to print large posters and documents
3D Printer - Prints 3D objects

Networking a printer Types of Printer Cables USB – Standard USB Printer Cable speed is around 12Mbps. 
Parallel – IEEE 1284 Standard Cable speed is around ane.5 to 2.77Mbps
IEEE 1284 standard supported the following:
Supports five modes of operation (Compatibility, Nibble Mode, Byte Mode, EPP and ECP) Supported a standard physical interface Serial – RS232 Standard Printer Cable speed is effectually 57Kbps
Supported impedance and termination
Supported a standard method of connecting a host PC and peripheral device
Network, or commonly Ethernet, connections are commonplace on network laser printers, though another types of printers do utilize this type of connection. Generally, network printers are designed to be shared using a central file/print server, though you can share them off a workstation in a "workgroup" environment. Parallel is the original standard for printers and a lot of bones printers however rely on the parallel port connection. A parallel (likewise called LPT port) sends and receives data simultaneously, transmitting data in parallel. Parallel uses a DB25 connectedness on the figurer side and an oddly shaped 36 pin connection on the printer chosen the centronics port.
Printer Connections 
Centronics
USB, or Universal Serial Bus, is a very mutual connector type for personal printers being sold today. USB is sold as the next generation of standard ports for computers. USB allows mice, keyboards, scanners, printers, most peripherals to connect to a computer. It supports up to 12 Mbps transfer rate and is hot swappable.
USB_A
USB_B
Infrared is not very commonly used. An Infrared acceptor allows your devices (laptops, PDAs, Cameras, etc) connect to the printer and ship print commands via infrared signals.
Series allows your printer to connect to your computer via the serial port.
Firewire is a high speed connection usually referred to every bit IEEE1394, its "standard". Though not specifically mentioned in the preparation outline for the exam, y'all should exist aware that a printer may connect via Firewire. Firewire is a high speed connection typically used for digital video editing or other high bandwidth requirements.
6pin Firewire port
Wireless connection such equally Bluetooth is also pop for connecting printers in a network environment
An HP Jet direct (or Printer Server Box) is a device which allows a non-networkable printer to be networked. For instance, we have an Epson color inkjet printer in our function which has a standard parallel port connection on information technology. The Jet Directly box allows the printer to exist connected into our network and allows the printer to exist shared off of our file/print server
