I purchased a Canon Pixma MG5350 and try to install the driver but this message appears on my screen: The system extension “/System/Library/Extensions/hpPlugInInit.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

It is the latest one and there are no more updates on this driver. What should I do?
