The greatest concern for an IS auditor reviewing a network printer disposal process is that evidence is not available to verify printer hard drives have been sanitized prior to disposal. This can expose sensitive data to unauthorized parties and cause data breaches. Disposal policies and procedures not being consistently implemented or business units being allowed to dispose printers directly to vendors are compliance issues, but not as critical as data protection. Inoperable printers being stored in an unsecured area is a physical security issue, but not as severe as data leakage. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 387
