I'm unable to print using hpcups-3.9.10 - cups reports it failed (as mentioned in summary) and I get: # /usr/libexec/cups/filter/hpcups Segmentation fault Downgrading back to net-print/hplip-3.9.8-r3 works perfectly fine.

Looks like reconfiguring the cups drivers solved this. Sorry for the spam :(
