This decision support tool calculates the total cost of operating a printer (less the price of paper, which is extremely volatile). While doing your research, make sure to verify that the printer model will accept a specific toner. Some companies (HP) will make similar models that cannot accept higher-capacity toner ink cartridges. This can lead to higher costs if you need to print large volumes. Conversely, if your printing needs are not that large, you can save money by purchasing the lesser model.
