Sticking to the order here (rather than the order at Tue, 13 Oct 2015
12:09:27 +0200), method 2; ie through GS and HP's hpcups filter to
convert the PDF to pcl3. I'm not sure what you mean by hidden.
Method 1 is expensive and, as you pointed out, still involves GS to go
from PDF to PS. Method 3 is what I am avoiding, in the sense of being
*in* the printing chain. Obviously I view PDFs in viewer, usually xpdf.

Does the PDF file you're viewing in evince look ok when you magnify it
on the screen? If so, what does method 2 produce when you print that
file? This should help isolate your problem.
