At GM Supplies, we understand that many people arent clear about the differences in toner/ink cartridges. Until recently, ink cartridges allowed printers to print documents quicker, and the number of pages per cartridge is greater than that of toner cartridges. However, huge strides are being made with toner cartridges, which are now being used for printing in color. Also, the number of prints per cartridge and the speed at which documents print is beginning to increase. Truthfully, the best way to make your decision is to determine which works best with your machine. Inks are normally liquid, while toner is more of a powder substance. You can check online with the make and model of your office equipment to see whether toner/ink cartridges are recommended. Today, you can buy any type of toner/ink cartridges you need online. Buying in bulk often helps you save money on these supplies, which can get costly. However, name brand and compatible products produce many copies and the quality of the documents you get is exceptional. Most toner/ink cartridges work in a variety of printers. For example, the Sharp ink cartridge black UXC70B is for use in a Sharp FOB1600, UXA1000, UXB20, UXB20CN, UXB700 and UXB700E. Another example are toner cartridges that are used for fax machines. The Brother Thermal fax toner cartridge PC101 works well for several models, including the Brother Intellifax 1150 and 1250, as well as the Brother MFC1750 AND 1850MC.
