Thank you for your response.  I tested the document again with all three pdf
programs, Okular, qpdfview and Evince. The pdf document has a dark blue title
and text in default black.  With Evince this all prints as expected.  With
qpdfview the colors are correct - except they are lighter - the blue appears as
a midtone and the text is dark grey.  With Okular the blue appears as a green
and the text appears as a grey.  So you may well be right.  It could be the way
Qt is interacting with the printer drivers.  I have also tested all three with
another document with a green title and body text in black.  All three programs
print the title as green - with Evince rendering a dark green and black body
text, qpdfview as the same but lighter and Okular as much lighter overall.  I
also notice that when I check the Options in Okular it is set to Greyscale by
default - which I change to colour before I print.  In the other programs
Colour is set as a default.
