The Other Solution
In some cases the icon of the taskbar and Finder does not show the path of the application.
For 3 hours looking for information on the subject 2 hours I got the simple solution. Excuse the spelling and writing, I am using a translator to make this response.
Applications> Utilities> Activity Monitor
There you will find the process of "Smart Panel", when selected, click on "Inspect" on top of Activity Monitor and then click the "Files and open ports. "
The first line shows the path Library> Printers> Samsung> SmartPanel
This path does not exist apparently in the Finder. In the Activity Monitor select the entire route and press ctrl + click on the path and we click on the "Reveal / Show". In Finder appears the application.
Before deleting it is necessary to stop this process in our Mac, in the Activity Monitor, close the window "Inspect", in the process list just to click on SmartPanel and click on the button "Quit Process" in top.
*Read NOTE at bottom* Now we can remove the application, I used AppZapper to delete all records. When you uninstall, I deleted the entire contents of the folder to make sure nothing is left of this application.
NOTE: It may not be necessary, but in my steps for uninstall, before stopping the process in the folder SmartPanel ran the 3 applications that had not remember the name because I deleted them, but only one of them worked , showing the viewing options icon in the Finder toolbar, uncheck the visualitazion option and then stop the process and remove it, leave it to your account.
SmartPanel short life!
