Ess Group - Xerox 850DP - Phaser Color Solid Ink Printer Manual

5.1.8.3.11 PRINTERNAME
This string variable is used as the commercial identification of the printer model. This value is used in
the INFO ID response, on printer test prints, and in many other interfaces to the printer.
5.1.8.3.12 RAMSIZE
This variable holds the number of bytes of RAM that the printer controller is currently configured with.
5.1.8.3.13 SCANNERTYPE
This variable indicates which, if any, scanner is currently attached and available to the printer
controller.

5.1.8.4 ESS Group

This group contains read only variables which detail the state of the printer controller itself.
5.1.8.4.1 PJL Status
This state variable has no PJL environment variable associated with it. It holds the current value of
the six digit HP-PJL status code. HP-PJL USTATUS DEVICE responses will be sent with this code
every time this status changes on all ports for which USTATUS DEVICE is enabled.
5.1.8.4.2 ESSSTATE
This state variable holds the processing state of the ESS. Possible states include:
• IDLE
• PROCESSING
• PRINTING
• ERROR
• INIT
• OPINTERVENTION
• PAUSED
When there is no activity in the ESS, the ESS is in the IDLE state. When the printing begins
downloading a job and the user job is scheduled and begins processing, the state moves to
PROCESSING. And clearly, when the first page of the job begins printing, the state should move to
PRINTING. If there are multiple jobs in the system, the most "mature" state takes precedence. For
example, if a job is processing and another is printing, the ESS State is PRINTING.
The ERROR state is entered when the ESS is currently experiencing an error which prevents it from
processing jobs. Such errors might include a firmware error, a hardware error, or non-communication
with the printer engine. The INIT state is used as the printer and ESS are booting. The
OPINTERVENTION state is entered when the printer requires operator intervention to proceed, such
as when manual feed media needs to be loaded, when a media mismatch condition occurs, or when a
response is required from the user to proceed in processing a job.
