This is a tracking bug for Change: IPP-USB as a weak dependency of CUPS and sane-airscan
For more details, see: https://fedoraproject.org/wiki/Changes/IPPUSBasPrintScanDependency
Add ipp-usb as a weak dependency of packages which provide support for driverless printing (cups), driverless scanning (sane-airscan) and driverless fax for USB devices capable of using driverless functionality (how to find out whether your USB device is driverless here), so such devices will work without a specific driver. ipp-usb design conflicts with the way how drivers work with the device, so a user intervention is required after upgrade.
