Clean Windows 11 prints normally; restoring the same system image breaks printing (0x000003e3)

Your testing proves the printer, cable, and clean Windows installation work; restoring the image reintroduces the failing software state. Error 0x000003e3 alone cannot identify whether the spooler, driver package, port monitor, or another service is responsible. On the restored image, unplug the printer, cancel queued jobs, and restart Print Spooler in Services. In Device Manager, enable Show hidden devices, remove Canon entries under Printers and Print queues, and delete the driver package when offered. Restart, then install the current Canon package before reconnecting USB. Run DISM.exe /Online /Cleanup-Image /RestoreHealth, followed by sfc /scannow, from an elevated Command Prompt. If printing still fails, test in a clean boot; success there identifies a third-party service conflict. If these steps do not change the result, Microsoft’s recovery path is reinstalling Windows. Migrate the grandmother’s data and settings rather than restoring that image, then create a new recovery image after printing is verified.
