16-4 Status Readback EN
A basic entity status request is shown in the example below. This
example identifies a status request for downloaded permanent fonts.
The example also includes a status readback response at the bottom.
Note that this example shows only one possible request/response; for
more detailed information, refer to the status readback command
descriptions provided later in this chapter.
In addition to the normal status responses, if an invalid request is
made, the printer returns an error response. Error responses are
described under the Inquire Status Readback Entity command, later
in this chapter.
