To all support

I gave up and zypper rm cups and delete /etc/cups on all linux machines

then I zypper in cups and reinstalled all the printers - now every app can print - don't know what broke but I seemed to have fixed it the hard way.

Something between 15.4 and 15.5 was not liked. The /etc/cups files were from leap 41.1 when I bought a new printer to replace a not supported anymore 16 year old HP.
