This seems to be a very common error related to the Samsung printer driver.
First, this is the error we're talking about:

Description: The SSPORT service failed to start due to the following error:
The system cannot find the file specified.
The Samsung driver installer adds a registry key for this service. The path can be found by looking for the SSPORT key in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services - it points to C:\Windows\System32\Drivers\ssport.sys
If you look for this file, though, it is missing. I tried searching the whole System32 folder and cannot find the file anywhere.
What we have found is that all of our Samsung printers work just fine even though the service always fails to start. Deleting the registry key gets rid of the annoying service startup notification failures.
Rather than delete the registry entry, though, I downloaded ServiWin and disabled the service. This allows me to see all of the services, not just what services.msc shows me. It also allows me to view the services by file name rather than the "friendly name".
