Character printers are devices that produce text and simple graphics by printing one character at a time. They typically use impact technology, where a print head strikes an inked ribbon against paper, similar to a typewriter. This method allows for clear and legible output, making character printers suitable for tasks like printing invoices or labels. These printers are often used in industrial settings and for specific applications, such as printing receipts or barcodes. While they may not offer the high-quality graphics of modern inkjet or laser printers, their durability and reliability make them valuable for certain business needs, especially in environments like warehouses or retail stores.
