The dot matrix printer was iconic in offices throughout the 1980s and 1990s in both Brazil and the United States, known for its distinctive loud printing sound and continuous paper feed. In Brazil, these printers remained common in banks and government offices longer than in the USA due to their durability and lower operating costs. The term is now largely nostalgic as digital printing has replaced this technology.
