I ran a dnf update of Fedora 29 today and it killed cups-pdf printer. I traced the problem to an update of ghostscript. I downgraded ghostscript returning cups-pdf to life. ghostscript- 9.24-1.fc28.x86_64 and/or its associated packages is the problem. ghostscript-9.23-1.fc28.x86_64 works fine. There 3 serious ghostscript bugs on Redhat Bugzilla (1628710, 1628875 and 1628943 reported on 9/14 and 9/13). Please go back to ghostscript-9.23-1.fc28.x86_64 until the bugs are cleared.

Please report it in bugzilla where the maintainer will see it and actually have a chance to respond.

I updated from updates testing to version 9.24-3 and it cleared the problem. I should have read all the open bug reports more closely before posting here. My bad...
