A printer driver is a software that is developed to help specific operating systems, like Windows 10, communicate with the Dell printer. If you give the command to perform a particular action, for example, print a page, your computer will convey the command to the printer via the printer driver. The printer driver is the main mode of communications between your Windows computer and your Dell printer, so much so that without the driver any printer you connect to your computer will not work smoothly. That is why it is very important to install the correct driver on your Windows 10 operating system if you want to run Dell devices and applications. You can contact Dell customer support number and consult a trained Dell expert to know which driver you need to install.
