According to page 1379 of the ZPL manual, the ZD500 printer series are the only desktops that support the device.cutter_installed SGD command.
To get the cutter installed status on a GX420t printer, use the ~HI command.
If it does have a cutter installed, it would return CUTTER in the last parameter.
More information about the ~HI command can be found on page 218 of the ZPL manual.
thanks for pointing that out - those who can read, have a clear advantage ;-)
