Study Notes
Printer Resolution
- Measured in Dots Per Inch (DPI)
- Determines print quality and text/graphic clarity
Types of Printers
- Impact Printers
- Use pins or hammers to strike paper and ribbon together
- Less expensive, fast, and can make multiple copies
- Types:
- Dot Matrix Printer
- Line Printer
- Drum Printer
- Non-Impact Printers
- Use electrostatic chemicals and inkjet technologies
- Produce high-quality graphics and varied fonts
- Types:
- Inkjet Printer
- Electrostatic Printer
- Laser Printer
- Electromagnetic Printer
- Electrographic Printer
Printer Speed
- Measured in Characters Per Second (CPS), Lines Per Minute (LPM), and Pages Per Minute (PPM)
Plotter
- A special output channel that produces vector graphics on paper
- Uses a pen, pencil, marker, or other writing tools
- Mainly used for large drawings, construction plans, and blueprints
Input/Output (I/O) Ports
- External interfaces for connecting devices to the computer
- Types:
- Parallel Port
- Uses eight or more data wires
- Data flows simultaneously through the wires
- Provides high-speed data transmission
- Used to connect printers to the computer
- Serial Port
- Transmits one bit of data at a time
- Used to connect devices such as modems and mice
- Parallel Port
Additional Notes
- Thin Film Transistor (TFT) is a type of field-effect transistor used in LCDs
- Chuck Hull designed and created the first 3D printer in 1984
