Th steps in MR-2651 are now correctly describing my actions. However, I am getting a different result, I’ll let the pictures speak for themselves:
However, I noticed something that may hold a clue: as soon as select an object and open the print dialog, the black edges change to colored ones, even before I check the “only selected objects” -box!
I tried changing the select color, without result.
Some of my settings:
Hope this helps,
Edit: Note that all my examples above are using “Display color” as the output color. “Print color” does not show the black edges at all, regardless of the visibility setting. “Black and White” shows black edges all the time.
It looks like the examples you showed in your MR-2651 write up are using black as the object color ( I cannot see your output color setting), which will always have black edges since that is the native edge color, so you would not be able to see the difference.
