Throw away everything you don't use
How to Completely Remove the Printer Driver from Your PC
If you’re constantly connecting to different printers in different locations, you probably don’t use all the printers installed on your device – probably only once or twice. However, your device ends up with many printers installed on it without you even realizing it.
Fortunately, you can delete any printer that you no longer use. However, the printer will not be completely removed from your device: the printer driver will remain in your device's inventory, in case you need it again later.
If you are sure you don't need it, you can remove or uninstall old, outdated, or uninstalled printer drivers and leftover driver packages or registry entries from your device.
