First off , you have some Windows updates waiting to be installed. Install them.
Secondly, there's a notification on your Action Center. What is it? Check to correct it.
And last , I'm not sure if Kaspersky works fine with Windows 7. Try Avast antivirus instead.
Now , since you have done the above and the problem persists, try re-installing your printer drivers of you have any. If not, please post back
