            Bug ID: 314755
           Summary: Fails to access greyscale option of printer (Canon
                    MG3150)
    Classification: Unclassified
           Product: okular
           Version: 0.15.4
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: h at loughrigg.me.uk

I have only ever tried to print twice from Okular.  Both times I wanted to
print a pdf in greyscale on paper and both times, it printed in colour.  I
cannot say whether this relates to just the pdf backend as I have never tried
to print from the other backends.  This bug differs from Bug 252596 which is
about printing to file in colour.  My printer is a Canon Pixma MG3150 but the
printer driver calls itself MG3100 Series and, its driver is available from
http://www.canon.co.uk/Support/Consumer_Products/products/Fax__Multifunctionals/InkJet/PIXMA_MG_series/PIXMA_MG3150.aspx?type=download&page=1
 but I found some extra lines of coding in a forum somewhere that make the
greyscale option available in the print dialogue box of most packages other
than Okular.

LibreOffice Writer prints greayscale suggesting that the bug is in Okular
rather than the driver

Reproducible: Always

Steps to Reproduce:
1.  Open a pdf.
2.  Press Ctrl+p and Printer Name defaults to MG3100-series.
3.  Click Options button.
4.  Choose the Options tab, check Greyscale and click OK.
Actual Results:  
A perfect colour print.

Expected Results:  
A perfect greyscale print.

My operating system is Kubuntu with KDE 4.9.4 but it also has Gnome installed.
