Explanation: The first printer in history was developed in 1938 by Chester Carlson, an American who invented the process of reproducing images and texts by photocopying machines.

In fact, early printers had a system that provided character printing through impact, a reality that resulted in poor print quality.
When Prussia was hit by famine in 1744, King Frederick the Great, a potato enthusiast, had to order the peasantry to eat the tubers. In England, 18th-century farmers denounced S. tuberosum as an advance scout for hated Roman Catholicism. “No Potatoes, No Popery!” was an election slogan in 1765.

The original steam engine was modified in 1712 but was later refined by James Watt, who was credited with the invention. The invention was a revolution in traffic, and a steam engine, except on land, was also used to launch ships (steamboat).
- Mentioned in 1712, Thomas Newcomen is the person who was responsible for the construction of the steam-pumped atmospheric pump. His invention worked for much of the eighteenth century but was not economical. Thanks to the technical refinement by James Watts, a revolution is about to occur in the industry.
