Installing old printer drivers (Canon Pixma MX850)

I would like to install drivers for MX850 on macOS Ventura. As expected, upon running the installation package I get prompted with an “incompatibility with current OS” error, which is obvious since the driver is for 10.0.3 or something like that. I disabled auth. root and SIP, then tried mounting. Returns: mount_apfs: volume could not be mounted: Permission denied mount: / failed with 66 I’m still unable to run installation package successfully.
