Software

Version 8.0.6

Even when I chose Output Mode = Black and White, KiCad still output and preview the print in color.

Maybe there was a bug in 8.0.6, but Kicad 8 finished at 8.0.9. You need to check 8.0.9 to see if the possible bug was fixed.

Also, Kicad is now up to 9.0.7. (well over one year later than 8.0.6). There appears to be no bug now.
