usb.device.device_unique_id

usb.device.device_unique_id

This command sets the USB Unique Device ID setting. The identifier that makes any printer unique is set by the
"usb.device.serial_string"
 command which is reported to the USB driver.
By default
"usb.device.serial_string"
 reports the printer’s serial number. If
"usb.device_unique_id"
 is set to
"off"
 the printer will report the
usb.device.serial_string
 parameter as its product family (e.g. ZT230, etc).
When subsequent printers of the same model, with
"usb.device_unique_id"
 parameter to
"off"
, are connected via USB, the host computer will not treat them as a new Plug and Play events, nor require new driver installations.
