| Action | Priority | |--------|----------| | Do not deploy the patched driver in production environments. | High | | Uninstall any existing patched version immediately if found. | High | | Use official HP Universal Print Driver (v7.0 or later) for full compatibility. | Medium | | If region/toner restrictions are the goal, consider HP’s “Toner Collection” program or third-party cartridges that mimic OEM chips without patching drivers. | Medium | | For legacy OS support, use network printing (LPR/IPP) instead of a patched driver. | Low |

Patched drivers can sometimes solve compatibility problems, but they carry meaningful security and stability risks. Whenever possible, use official HP drivers, OS-provided drivers, or HPLIP (Linux). If you must use a patched package, follow strict safety steps: vet the source, scan files, test in isolation, and keep backups.
