Getting your printing costs down is practically a new year resolution every year, but this time it really can be done if you find a good toner blog to give you the leading edge on your competitors. Most businesses that buy their toner and printing accessories do so through vendors, and usually take whatever the vendor says as light and truth. This is a terrible way to conduct business.
You should be critical of everything your vending service says, especially if they are trying to entice your company into a contract extension. The way vendors even stay in business is by inflating the prices of basic materials they received from a wholesaler. This takes care of their own profit and overhead while eating away at yours. There are far better solutions than working with vending firms.
A good toner blog can tell you all this, as well as how to achieve freedom. When you bought the printers used in the office, the odds are good that the manufacturer warned against working with anyone but licensed vendors. They also probably emphasized the dire consequences of using parts or accessories that were made by third party providers.
In reality, nothing bad will happen if you shop around for your toner cartridges instead of going by the company line of only buying the ones made by the original manufacturer of your printers. These are usually grotesquely overpriced and offer no greater performance than any other competitor cartridges. Shop around and compare prices to realize the difference.
