The printer cartridge works by storing ink inside of it to be used by the printer. When the printer sends a cartridge and appropriate signal, the ink is dropped and shaped into the form of the image or letters needed to be translated onto the sheet of paper. It is important to note, that two separate cartridges are needed for those who need color on their printed pieces. One cartridge will have only black ink and will only function during black and white printings, while the other contains red, yellow, and blue ink and can create different color combinations. The color cartridge is, in general, much more expensive then the simple black cartridge, so it is important not to waste it. It is a good idea, therefore, to not waste color ink unless it is absolutely needed.
Fortunately for owners of printers, there are other options becoming available. Brands such as Xerox offer cheaper alternatives for printer ink that can work in multiple printers. Because these brands do not create printers themselves, they have no reason to charge more for ink and therefore can offer everyone a better alternative. The best way to find a good option for your printer is to check with a local store to see what different printer cartridges are compatible with your printer.
