Update of bug #53073 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #4:

Confirmed.  Apparently when printing a few black pixels get mixed in which
causes the overall color to appear darker.

As a test I used


plot (1, 'o-', 'linewidth', 4)


I used a screen magnifier to zoom in on the Qt window and then used a
screenshot tool to capture the magnified window.  Attached are the pre- and
post-print pictures.
