In such a case, you will find that the manufacturers will make improvements to drivers just the way a software developer upgrade a program. Besides this, there are cases when such upgrades can make the older drivers outdated. Similarly, a driver that is updated can heal a wide range of errors and behavior problems i.e. tolerated by a particular device. For instance- if your printer is not functioning properly, you can simply fix the issue with the help of a driver. This is as simple as downloading the corresponding driver by checking a manufacturer’s website.
