[arch-general] cups hangs while adding a new printer

Hi, on a Thinkpad X270 I'm trying to add a Epson XP 245 using epson-inkjet-printer-escpr2. Unfortunately cups just hangs with "Unable to get list of printer drivers", "lpinfo -m" just hangs and after some time outputs "Success". Searching around showed people already had this issue with foomatic, but neither foomatic nor gutenprint are installed. So the explanation of "generating the ppd list takes too long" should not fit here. And for adding more confusion, on another system where even gutenprint is installed, it works fine - so it's not a general issue. Any ideas? Best Regards Bjoern
