If the only goal is to plot the drawing, the perfect way is to have the right plotstyletable,
create a copy and set all plotstyle colors to black.

(if (zerop(getvar "PSTYLEMODE")) "MYSTBPLOTSTYLETABLE.stb" "MYCTBPLOTSTYLETABLE.ctb")
>>"Some of the drawings are .stb styles and they cant print in monochrome if they are "True Colors"
Thats' wrong, STB are the only way to plot a (true)color in another color by plotstyles,
just the stupid CTB are limited to the 255 ACI colors as plotstyles, STBs not.
You can not print an TrueColor Object in Black by using a CTB.
So i am not sure to understand. You know that? So please explain it one more time for me
how you think you can "fix" the problem.
My Q: Is there only one Plotstyle in use (the NORMAL), or do you have the right STB plotstyletable?
PS: A BLACK/WHITE printer (or a driver, set up as black/white only) can print all black.
>>" Is there some way to make the script that it can determine if it is ctb and if its not use CONVERTPSTYLES to change it to ctb style. Sorta like an If statement."
Use my IF statement above, change the THEN part, delete the ELSE part, add it above your PLOT statement.
(if (zerop(getvar "PSTYLEMODE")) (command "_CONVERTPSTYLES"))
And then? You don't have a ctb Plotstyle "255,200,200" to set them black.
If all object colors are ByLayer, you can change the color of Layers easily for modelspace,
but also in stb drawings.
