Custom monitors for print spooler stability

Overview

Print spooler crashes still plague LOB apps—detect before users chain-call.

Signals

Spooler service not running, queue depth > threshold, recurring driver isolation events.

Auto-remediation (careful)

Restart spooler once; if repeats in 24h escalate—avoid infinite restart loops masking malware.

Root causes

Bad driver, corrupted jobs, PrintNightmare mitigations conflicting with vendor requirement.
