This software update keeps popping up almost everyday in my iMac 27 although I keep updating. Looks like the either the update is not happening on my machine or some other problem. Anyone else know of this?

This software update keeps popping up almost everyday in my iMac 27 although I keep updating. Looks like the either the update is not happening on my machine or some other problem. Anyone else know of this? Everytime I check for updates (I have the setting to manual check), an alert pops up in Apple store with the phrase "Lexmark Printer Software Update 2.11" available for download.

Is there a way I can turn off this notification for Printer updates until it is resolved? It is pretty annoying.

Thanks
