Samsung Toner – Samsung Toner Cartridges – Toner for Samsung
Samsung Electronics Corporation is the world’s second-largest manufacturer of high quality color and monochrome laser printers and toner cartridges, as well as multifunction machines. Samsung is second only to HP, which has long been the #1 provider of HP brand printers and HP toner products. However, other competitors, like Xerox, provide alternative products to traditional toner technology, like Xerox ink.
Since they own the entire printer and toner cartridge manufacturing process, Samsung has a significant competitive advantage over companies who are dependent upon other vendors for core hardware and software components. For example, Samsung toner cartridges can be developed so that the same cartridge profile can fit into many different printer configurations, thus lowering the cost of development.
Samsung also offers color laser printer customers a free one-year on-site service program in the sub-$700 color laser printer category, a service that must be purchased separately for most competitors’ products. However, the warranty may not cover some consumable components, like Samsung’s toner cartridges. Both brand name and compatible or remanufactured cartridges can easily be found at online stores.
Samsung’s color laser and monochrome laser printers have established a reputation for providing a lot of bang for the buck. These printers are reliable, produce acceptable text and graphics quality, are easy to use, and have solid performance within their respective printer class category. For example, the Samsung CLP-300n is a work group class printer with a very affordable price, but with big features, including fast printing speeds and network-ready capability. The Samsung color toner cartridges can be quickly installed directly into the back plane of the printer.
Brand name Samsung toner cartridges are available from virtually any retailer of Samsung products. However, less expensive versions are available which can reduce the cost of ownership by as much as 60%. Due to inconsistency in quality, consumers must be careful to purchase non-brand laser toner cartridges from reputable companies like Ink Technologies.
