I saw this fix over in the Super User forum:
Ran into another cause for this error. In my case I was working with a system that turned out to be heavily infected with adware and a few virus signatures. Not sure which but it appears at least one of them was intentionally blocking teamviewer so as to prevent remote support? Had to fall back to an alternative remote software (Remote Utilities) to clean it up with Malware Bytes and Avira (AVG wasn't cutting it I guess?) and then TeamViewer started working again.
Also- this site compiles a bunch of different fixes.
There are many way to fix this error, I just sharing one the easy method which can done by command prompt. So follow this and cure it

While working with the Canon printers, you may get Canon Printer Error B200 suddenly. This error is very common on most of the newer models of Canon printers. Apart from MG5220 printer, the users can also face the error while using MP6320, MP870 etc. Due to a faulty printer’s ink head, such an error takes place.
