This setup works for a cheap Chinese no name brand Cutting Plotter I use.
On the host PC add a new printer and set the printer model to “Raw Queue“
Set the device URI to, for example, serial:/dev/ttyUSB0?baud=9600. This assumes the servial device is attached to USB port 0.
Make sure it is shared.
On the slave PC simply add the network printer
