This is because the final filter did not complete.

Thanks. I get exactly the same as you. It shows the system being unable
to move on to the final filter, epson-escpr-wrapper. It also appears to
show Ghostscript not carrying out a conversion with the filter
gstoraster. I have observed the same behaviour on Jessie and with other
PPDs from the same package.

You error_log also backs up wf2530.log by showing epson-escpr-wrapper
reporting "Cannot get option of PIPS" and

  D [24/Oct/2016:19:38:57 +0200] [Job 90] PID 32749 (/usr/lib/cups/filter/epson-escpr-wrapper) stopped with status 1.
  D [24/Oct/2016:19:39:01 +0200] [Job 90] PID 32747 (/usr/lib/cups/filter/gstoraster) stopped with status 1.

Unfortuately, my error_log show nothing of this. There is no mention of
PIPS and epson-escpr-wrapper and gstoraster complete successfully. I
have no explanation for this difference.

My print queue was set up (all on one line) with

  lpadmin -p wf2530 -v file:/home/brian/wf2530 -E 
    -m escpr:/0/cups/model/epson-inkjet-printer-escpr/Epsom-WF-2530_Series-epson-escpr-en-ppd

and I printed with

  lp -d wf2530 /etc/nsswitch.conf

You could try this to see whether it gets printing going for you.

Cheers,

Brian.
