How do I use a plug in?

I have a proprietary graphics program (Color Byte, by CADLink) which installed a plug in into my CorelDRAW2018.   They no longer support it and will not supply any information on how to access or use it.  I believe (assume?) it will allow one to print directly to their RIP from CorelDRAW rather than several steps I now have to perform.

The following files are those to which I refer:
     C:\Program Files\Corel\CorelDRAW Technical Suite 2018\Draw\Plugins64\corToSignLab7S4.cpg
     C:\Program Files\Corel\CorelDRAW Technical Suite 2018\Draw\Plugins64\corToSignLab7S4.ini

Anyone have any specific knowledge on this plug in?  Or, general knowledge of how to access/use a plug in?
