The working principle of most typewriters is to stamp characters onto a page with special levers with metal or plastic base. When the corresponding key is pressed, the lever will touch the ink absorbent tape, thus leaving the imprint of the letter on the paper appearing. Before the next character is printed, the sheet of paper is automatically moved (and as a rule the ink ribbon is also moved to replace the new line section according to the letter). To print multiple copies of the same document, sheets of carbon paper inserted between sheets of common paper are used.
The first commercial typewriters were introduced in 1874, but they were not popular in offices until the mid-1880s. Typewriters quickly became a practically indispensable tool for all. both writing jobs in addition to personal handwritten letters. They have been widely used by professional writers, in the office and for home business correspondence. With today’s modern speed service technologies, the typewriter has been completely replaced and is rarely used.
