A user reports that all printouts to a locally attached printer show only garbled characters. Which of the following tools should a technician use to troubleshoot the issue?

Programs and Features is used to uninstall applications and Windows features, not to diagnose or manage hardware driver issues.

Performance Monitor tracks system resource metrics such as CPU and memory usage and is not relevant to diagnosing print output quality.

System Configuration (msconfig) manages startup programs and boot options and has no capability for troubleshooting printer driver problems.

Device Manager provides direct access to the driver stack for all hardware including locally attached printers, allowing a technician to view driver details, update the driver, roll back to a previous version, or uninstall and reinstall it entirely. Garbled characters are a classic symptom of a corrupt, mismatched, or incorrectly installed printer driver, since the driver is responsible for translating print jobs into the correct command language for the hardware. No other listed tool provides driver management capabilities.
