That sounds like a good idea. What about "Grayscale option ignored when
generating print data for PDF document"?
(Note that I don't seem to have the permission to change the title myself,
since I am not the reporter of the bug).

Great, thanks for the update. Would you like to change the title accordingly,
since printing to a real printer does work now?

> Should we close this as RESOLVED UPSTREAM, then?

While printing to real devices should yield the expected result now, Okular
itself still does not take the color/greyscale into account when generating the
print data (by default, s. Oliver's comment 5 for rasterized printing), which
also leads to "Print to file (PDF)" still not yielding the expected result.
(Sorry for not mentioning that more explicitly in my previous comment.)

Unless this is handled by a different bug report, I'd therefore leave this one
open for now.

Note that the "Advanced" options tab has been reintroduced for the current
development version of Qt 5 [1]. Also, the problem with duplex [2] and color
[3] options being set at different places has been fixed, so I'd expect that
the problem should be solved with those Qt upstream changes (will be part of
the upcoming Qt 5.11) for the case where a real printer is involved.

As a workaround, if you have a recent version of Okular [0], grayscale printing
should work if you set the 'force rasterization' option.

[0] You need the patch 0c4c2ddbbc5e509c69b72c99bf6e83a356669eba , which dates
from August 4th, 2017

I can confirm both issues on openSUSE Leap 42.3. If either the greyscale option
worked OR the advanced printing tab was there, it would be possible to print
greyscale PDFs. As it is, CUPS defaults need to be changed instead, and that's
way too involved for such a simple task...

I can confirm this in Opensuse Leap 42.3 using
- kde-print-manager-17.04.2-1.1
- okular-17.04.2-1.6
- Plasma 5.8.7
- plasma-framework 5.32-0-4.1
- libQt5.6.2
- kdelibs-4.14.33

In evince it works though using gtk oder gnome(?) print dialog...

Is this related to https://bugreports.qt.io/browse/QTBUG-54464 ?
