A user states that every print job submitted to a local printer prints out random characters. Which of the following steps would MOST likely resolve the problem?
The correct answer is C. Reload the printer drivers. Random or garbled characters from a printer consistently indicate the printer driver is corrupt or incorrect, causing the OS to send malformed data to the device.

Why each option
Random or garbled characters from a printer consistently indicate the printer driver is corrupt or incorrect, causing the OS to send malformed data to the device.
Rebooting may temporarily clear a stuck queue but does not address the underlying driver corruption causing garbled output.
Clearing NVRAM resets printer configuration settings and network parameters, but does not fix driver-level data translation errors on the host computer.
The printer driver is responsible for translating print jobs into a language the printer understands (such as PCL or PostScript). A corrupt, outdated, or mismatched driver causes the printer to receive unintelligible data, producing random characters. Reloading the correct driver restores proper translation of print data.
A faulty cable would more likely cause the print job to fail entirely or produce incomplete output, not consistently random characters.
