[Groff] Color and older PS printers

[Mike Bishop]

     I have an aged QMS PS 410 laser (along with others) on my
     network.  Postscript generated with the 1.18.1 groff failes
     to print on this device--that generated with 1.17.2 has no
     problem.

     A diff between files generated by each version (with the -c
     option on 1.18.1)) gives assorted setxxxcolor/setgray etc.,
     commands.  The QMS printer reports "Postscript Version
     52.4".

     So, /should/ older PS printers work, or is their some other
     method for defeating color on some printers, not on others
     (for example, some special option to grops)?

Thanks,
