1. Dot matrix printer, ribbon. Dot matrix printer ribbon, divided into wide and narrow. Some ribbons can be replaced individually, and some ribbons must be replaced together with the ribbon holder. The ribbons of different colors can be replaced as needed;
2. Laser printer, toner, toner cartridge. The toner and toner cartridge of some laser printers can be separated. After the toner is used up, the toner can be easily filled, and then continue to use until the toner cartridge is aged and replaced; for some laser printers, the toner and the toner cartridge are integrated, and the toner is used up. After that, the toner cartridge should be discarded, resulting in a certain waste. The cost of the toner cartridge accounts for a large proportion of the cost of the whole machine.
3. Inkjet printer, ink, one-piece ink cartridge. Inkjet printers, depending on the printing color, have 4 colors, 5 colors, or 6 colors, etc. The printer ink can generally replace the ink of one of the colors, and it does not have to be like the inkjet printers in the early years. When one color of ink is used up, it needs to be replaced together with the remaining colors, resulting in waste. After some printers run out of ink, as long as the used ink is replaced, the print head can be used permanently. The advantage of this type of printer is that the cost of changing ink is low. The disadvantage is that if the print head is used for many times, the print quality will be reduced. It is also prone to the problem of blocked nozzles. In severe cases, the printer needs to be repaired or scrapped; some printer nozzles and ink cartridges are integrated. When replacing ink cartridges, the nozzles at the bottom of the ink cartridges are also replaced together. The cost of such ink cartridges is relatively expensive. , The advantage is that this kind of printer will not have the problem of nozzle blockage. If it is blocked, after replacing the ink cartridge, the printer can still be used, and the print quality can be maintained beautifully.
Relatively speaking, the use cost of the ribbon is the cheapest, and the disadvantage is that the printing effect is not ideal, and it cannot print color graphics; the toner and toner cartridges of laser printers are the most expensive to use and have the highest printing accuracy, but the color effect of printing is not as good as that of inkjet. Printer; inkjet printer ink and ink cartridges, the use cost is moderate, the printing color effect is the best, and the printing accuracy is high, but the general inkjet color retention is not as durable as the laser, and it is easy to fade for a long time, and it is easy to be affected by moisture.
