I recommended this step

1. do printer troubleshooting

2. Uninstall antivirus using removal tools (Kapersky)

3. Registry trick as JSB43211 suggested, backup your registry before perform this

1. Open Regedit as Administrator 
2. Find the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\ key. 
3. If you are on a 64-Bit machine, browse to the "Windows x64" sub-key (else "Windows NT x86") 
4. Under the "Print Processors" sub-key DELETE ALL THE SUB-KEYS EXCEPT "winprint" key 
5. Start the Print Spooler service. 
6. Test to see if you can Add a printer.
