The “N” in CAN stands for network, after all. The trick is to create a device ID for each desired CANSerial interface, which is done in his library using the usual Arduino setup step.

After some research, it was determined that it would be relatively simple to have an Arduino convert incoming serial data into a parallel output to the printer.

Since you lacked the USB interface in your own Arduino board, it becomes necessary to use a homemade/ready-made USB to Serial Converter Module as an efficient and economical solution. Inexpensive and ...
