Blue Chip Word Processor by Visiontronics and Professional Software, Inc. Designed by Jacques Lebrun (1984) - This is the word processor that accompanied the Blue Chip D12/10 daisy wheel printer.  It's a fairly capable application, supporting 40, 80 or 120 columns. Thank you Thomas Shaw for sharing this!
