7 Printers and Peripheral Hardware
Learn how printer types form images, how peripherals support computer input and output, and how to connect, configure, and troubleshoot these devices.
types
Printers produce paper or label copies of digital information. They form images in different ways, which makes some types especially suited to particular printing needs.
: Sprays tiny droplets of liquid ink onto paper. It is commonly used for color documents and photos.
: Uses electrostatic imaging and heat to fuse toner powder onto paper. It is often chosen for fast, high-volume text printing and may print in monochrome or color.
: Strikes an inked ribbon against paper to form characters from dots. It is useful where multipart forms or duplicate copies are needed.
: Uses heat on special paper or ribbon to create an image. It is common for receipts and labels.
A combines printing with one or more functions such as scanning, copying, or faxing.
functions
A is hardware connected to a computer to provide input, output, storage, or communication. A device may serve more than one function: a scanner sends image data to the computer, while a multifunction can both scan and print.
Input: Keyboard, mouse, webcam, microphone, and scanner.
Output: Monitor, speakers, headphones, and .
Input and output: Touchscreen, multifunction , and headset.
Storage: External hard drive, flash drive, and memory-card reader.
Communication: Network adapter, Bluetooth adapter, and modem.
Connect and configure devices
Before connecting a device, check its power needs, ports, cable, and operating-system compatibility. Choose a connection method supported by the device and computer.
: Connect the device to a suitable computer port. A -C-shaped connector by itself does not guarantee a particular data speed or power capability; those depend on the device and cable specifications.
Wi-Fi or Ethernet: Connect a network-capable to the network, then add it from the computer. For wireless discovery, the computer and generally need to be on the same network.
Bluetooth: Put the into pairing mode, then use the computer’s Bluetooth settings to find and pair it. Follow the device’s instructions if a pairing code or confirmation is requested.
For a Windows , open Settings > Bluetooth & devices > Printers & scanners, choose Add device, and select the . Windows may install a compatible driver automatically. If a driver is needed, use Windows Update or the manufacturer’s official support site. Print a test page to confirm setup.
For other peripherals, check the operating system’s device settings to verify that the device is detected and selected for its intended role, such as choosing the correct microphone, speakers, or default . A is software that lets the operating system communicate with hardware.
Troubleshoot common problems
Troubleshoot in stages: check power and physical connections first, then settings, drivers, and the device itself.
not found or not printing
Confirm that the is on, has paper, and displays no error. Check that cables are firmly connected or that the is connected to the expected network.
For a wireless , verify that it is on the same Wi-Fi network as the computer. Restart the and, if needed, the computer or router.
Confirm that the correct is selected in the print dialog and that it is not paused or set to Use Offline.
Check the print queue. Cancel a stuck job, then try printing a test page.
If the remains unavailable, remove and add it again, and check for a compatible driver through Windows Update or the manufacturer.
Poor print quality or paper jams
For faded, streaked, or blank pages, check ink or toner levels and use the ’s maintenance tools, such as printhead cleaning or alignment, if available. Make sure the selected paper type and print settings match the loaded paper.
For a paper jam, follow the ’s instructions to remove paper gently; forcing it can damage the . Check that the paper is loaded straight and that the tray guides fit the paper.
not detected
Try a different compatible cable or port, and reconnect the device. For a Bluetooth device, ensure Bluetooth is enabled, the accessory is charged, and it is in pairing mode. Check device settings and driver status; install updates through the operating system or the manufacturer’s official site.
If a device works on another computer but not this one, the problem may be with the original computer’s port, settings, or driver.
