- Laser printers used laser technology for faster, higher-quality prints but were expensive.
- Wi-Fi and Bluetooth for printing from smartphones, tablets, and cloud services.
- Laser and inkjet printers with resolutions up to 4800 dpi.
- Multifunction printers combine printing, scanning, copying, and faxing in one device.
- Energy-efficient designs and ink-saving modes.
- 3D printers create three-dimensional objects from digital files, used in prototyping, manufacturing, and even medicine.
Typewriters
- Mechanical devices used for writing text on paper. They featured individual keys for each character, which struck an inked ribbon to imprint letters onto paper.
- Early models were manual, while later versions included electric typewriters.
- No editing capabilities (errors required correction fluid or retyping).
- Limited formatting options (e.g., no bold, italics, or fonts).
- Heavy and bulky design.
- Typewriters have largely been replaced by computers and word processors.
- Modern typewriters may include USB connectivity for saving documents digitally.
- Some are designed as minimalist, retro-style devices for creative writing.
- No longer mainstream but valued for their tactile feel and simplicity.
Vacuum cleaners
- Manual vacuum cleaners (e.g., hand-pumped models) in the late 1800s.
