Gutenprint 5.2.12 is now available in the openSUSE Build Service (OBS) project "Printing" e.g. for direct RPM download from http://download.opensuse.org/repositories/Printing/ S. B. please test it and provide feedback whether or not Gutenprint 5.2.12 from the OBS "Printing" project works for you. If it works for you, I will forward Gutenprint 5.2.12 from the OBS "Printing" project to "Factory" so that in the end Gutenprint 5.2.12 appears in "Tumbleweed". In general see the section "Version upgrades for printer driver packages" in https://en.opensuse.org/SDB:Installing_a_Printer and see https://build.opensuse.org/project/show/Printing
