The Canon iR2270 and Canon iR2870 are models in Canon's imageRUNNER series of multifunctional printers/copiers. These devices can handle printing, copying, scanning, and sometimes faxing, typically used in office environments.

The Windows driver for these devices is software that allows your computer to communicate with the printer or multifunction device, ensuring that your print jobs are sent to the printer with the correct settings, such as paper size, print quality, and other configurations. The driver also helps manage features such as scanning or faxing, depending on the functionality of the specific model.
