In the years I’ve been monitoring and maintaining systems for consignment store owners, I’ve found ConsignPro (CP.exe) has a propensity to crash at the end of the day, when closing.
A client that utilizes ConsignPro, purchased a new HP printer. I installed & networked it between her two systems. I forgot the client utilizes a plain-paper printer to print tags/labels, as opposed to a tag printer — e.g. a Zebra thermal tag printer.
