Thank you very much Bob. That was the key to the whole puzzle. As
soon as I set them to use hardware flow control everything worked as
expected. I appreciate the technical expertise that you bring to this

Since it is a serial printer, this sounds like a handshaking issue (also
known as flow control).
First, you'll need to know what serial parameters the printer is set for.
Go to the printer manual for that. If the printer is set for "CTS" or
"DTR" flow control, these are hardware methods, as opposed to software
methods (such as Xon/Xoff). If the printer uses a hardware method, then
the wiring of the printer cable is critical. This stuff is a pain, but it
is required for serial interfaces (which are over 30 years old).

All things considered, it is probably time to make this pronouncement:
DON'T BUY SERIAL PRINTERS.
