So now I am very suspicious.
First (previous fix I reviewed) Job Sheets weren't supported on 16.10, 
now its PageRanges.

I think this merits investigation of what is going on before we commit 
this fix.
Why are attributes that have always been supported by CUPS suddenly 
unavailable ?

And for the cases we image the pages ourselves, we can implement PageRanges
internally, so for a normal PrinterJob it always can be supported .. 
regardless of
what the printer says.
