Printer consumables refer to the materials used in printers to produce printed documents. The most common consumables include ink cartridges, toner cartridges, and printer paper. These items are essential for the printer's operation and directly affect the quality of the printed output. In addition to ink and toner, other consumables may include drum units and print heads, which can also wear out over time. Regularly replacing these items ensures that printers function efficiently and maintain high-quality printing standards. Proper management of printer consumables can help reduce costs and improve overall productivity.
