Printer driver software lets your computer interact with the printer and helps it run smoothly. Without the correct drivers, your printer might not function properly or have issues. Printer drivers convert data into a format the printer can understand to complete printing tasks. If your system doesn’t have the right driver software installed or is installed improperly, it won’t be able to detect your printer and print anything.
