[cups] only one machine won't print

[hymie!]

In our last episode, the evil Dr. Lacto had captured our hero,
  Helge Blischke <helgeblischke at web.de>, who said:
> Did you install the cups-filters package from openprinting? 

I just installed the cups-filters package.

Now I get a new error  "Filter failed"

But I don't know which filter or why it's failing.

I found this line in my error log
d [21/Jan/2016:07:29:03 -0500] [CGI] cgiSetIPPVars(response=0xb77f0928, filter_n
ame=\"(null)\", filter_value=\"(null)\", prefix=\"(null)\", parent_el=0)

but I have no idea if it's relevant or not.
