Universal Serial Bus (USB) Device Communications
The printer is a terminal device (not a host or hub) when using a USB interface. You can refer to the USB Specification for details regarding this interface.
Scanners, scales or other data input (terminal) devices must use the serial port (not the USB port) to send data to the printer.
Serial Port and Windows® operating systems
The Windows operating system default settings for the serial port communication closely match the printer’s defaults settings with one exception; the data Flow Control settings. The Windows default data Flow Control setting is NONE. The printer requires data Flow Control set to Hardware.
Note • The printer does not support Windows® Serial Port Plug and Play (PnP) device detection at this time.
