cups-filters shall be a dependency.
https://github.com/void-linux/void-packages/pull/41923

Description:
Without cups-filters, one may encounter problems such that one cannot print anything through cups. See for example [1], although it was reported on FreeBSD, the same issue happened to me using Void Liunx.
