Hi Teri Graffia,
Your HP uses a Snapdragon X ARM-based processor, so the “not supported” message most likely means that the Canon installer or its driver was designed for Intel/AMD-based Windows PCs rather than Windows on ARM. This is not related to the amount of RAM or available storage.
One important distinction is that Windows 11 on ARM can emulate many x64 applications, but a hardware driver still needs to support the ARM64 platform. Therefore, compatibility should not be assumed solely because the scanner supports Windows 11.
You can first connect the scanner directly to the computer, then go to Settings > Bluetooth & devices > Printers & scanners > Add device and check Settings > Windows Update > Advanced options > Optional updates for a scanner driver. If Windows detects the scanner, you can then try scanning with the Windows Scan app.
If no driver is offered and the scanner is not detected, I recommend contacting Canon Support to confirm whether an ARM64-compatible driver is available for the CanoScan LiDE 300. Without a compatible driver from Windows Update or Canon, the scanner may not work with this ARM-based computer.
