A printer is hardcopy device that outputs texts and images on paper. Printers have been around since the early days of computer. The first printers were actually typewriters and teletypewriters that were adapted to print binary data. These printers were often slow and noisy. Today, these are printers that print entire pages of text and/or graphics at astonishing speeds.
Printer quality available from the hard copy output varies considerably.
1. Letter quality print: Letter quality print is made using fully formed characters and is obtained by striking with the hammer containing fully formed solid line characters and symbols.
2. Near-letter quality print: Near-letter quality print obtained from dots that arrange they to form alphanumeric characters. Print head makes multiple passes over the same letters filling in the space between dots or lines.
3. Standard quality print: Standard quality print quality is produced when characters composed of dots are formed by a single pass of print head.
4. Draft quality print: Draft quality print is the lowest quality print in which the characters are formed by using minimum number of dots. Draft quality print is suitable for rough draft.
Features Determining Print Quality
1. Resolution: All printers work by laying down tiny dots of ink, toner or dye. The dots are so small and close together that they fool your eye into thinking its seeing solid images. The finer the dots, the better the image quality. This characteristic is known as “Resolution“. Resolution is measured in linear dots per inch, or “dpi”. Medium quality inkjet or laser printer can print 300 or 600 dip. The best quality printer can have the resolutions of 1200 to 1800 dip.
2. Speed: Printer speed is measured in either character per second (cps) or pages per minute (ppm). Normal laser printer can have the speed of 4-24 ppm.
3. Duty cycle: Duty cycle, which is generally expressed in pages per month, refers to how hard you can work printer before it breaks. Heavy Duty cycle printers are required for offices having large volume of works.
Types of printers
Printers are classified as impact or non- impact printers, depending on the method used to print the characters on the paper.
1. Impact printer used hammers or prints to strike and inked ribbon and the impact then cause and image of the character to be printed on paper. Impact printers functions just as typewriter do.
2. Non-impact printers do not make contact with paper or ribbon during printers printing. They use several technology for printing, such as xerographic, electrostatic, electro sensitive, electro thermal, ink jet, and laser. Non impact printers are the fastest of printers with speeds approximation 20,000 lines of print per minute. They are also much quieter than impact printers.
