1. Topic: Types of Printer Presented to: Mam nuzhat akram

2. Printer Output device. Produces paper copies of digital documents. Converts electronic data into a physical form on paper or other media. Electronic data is often image or text. P rinted output produced by a printer is often called a  hard copy. P hysical version of an electronic document . Most modern printers can produce color prints , and some even create high-quality photo prints that rival professionally developed photos

3. Impact printers Components of Impact Printers: Print Head : Impact printers have a print head with pins or hammers. Ink Ribbon : The ink ribbon is usually made of fabric or plastic saturated with ink. Paper Feed Mechanism : This feeds paper through the printer. Printing Process : The print head strikes the ink-soaked ribbon, pressing it against the paper. The force of the impact causes the ink to transfer from the ribbon to the paper. This direct and forceful action allows impact printers to print through multiple layers of paper simultaneously.

4. Advantages of Impact Printers : Reliable : Impact printers are tough and ready for big printing jobs. Precise and Durable Prints : suitable for various paper types. Low cost . Common Use Cases : Impact printers are commonly used in warehouses retail stores , and offices where documentation in multiple copies is frequently required. Epson FX-890N Impact Printer

5. Disadvantages of impact printers Impact printers are noisy during operation. They are slow. S peed Range: 200-600 CPS.   Impact printers produce only black-and-white output . Many use outdated technology . Manual Paper Handling. Despite these limitations, impact printers remain reliable for specific tasks working of impact printer and noise

6. Types of impact: Character printers A printer that prints one character at a time . Example: Dot matrix and daisy wheel Line printers A  line printer  prints one entire line of text before advancing to another line. Example: Drum printer and chain printer.

7. Dot matrix printer Processing: Dot matrix printers use a matrix of pins to create characters by striking an inked ribbon against paper. Typical Uses: Invoices , receipts, and industrial settings. Example : Older models like the Epson LX-350 Epson LX-350

8. Daisy wheel printer Processing: T hey have a rotating wheel with embossed characters. The wheel strikes the paper to create text . Typical Uses: Word processing and letter-quality printing. Example : Brother GX-6750. Pros : Precise character output. Cons : Slower than other printers . Daisy wheel Daisy wheel printer

9. Non-impact printers   They produce text and images without direct physical contact between the printing mechanism and paper.  Excel in speed, operate quietly, and require less maintenance. Examples: Inkjet printers, laser printers and thermal printers etc. (Non-impact printers)

10. Pros and cons Advantage : less Maintenance : Fewer moving parts, less need for repairs. Quiet Operation : No noisy impact. Speed : Faster printing. Superior Print Quality : Sharp text, vibrant colors. Versatility : Handles various paper sizes. Disadvantages: Costly Consumables : Expensive ink/toner. Heat Sensitivity  (for thermal printers). Toner Hazards  (laser printers). 

11. Inkjet printer   Inkjet printers spray tiny droplets of ink onto paper to create text and images. Typical Uses : Home printing, photo printing, and occasional document printing. Pros : Good color quality, versatility. Cons : Slower than laser printers. Example : The  Epson Eco Tank   series. Epson Eco Tank

12. Laser printer  Laser printers use a light beam to create an electric image on a drum, which transfers toner onto paper. Typical Uses : Offices, businesses, and high-volume printing. Pros : Fast, sharp text quality, cost-effective for high-volume printing. Cons : Typically monochrome (black and white). Example : The  HP LaserJet Pro   series. HP LaserJet Pro
