Printer Job Language Technical Reference Manual - Business ...

STATUS Category
The INFO STATUS command returns online status (TRUE=online,
FALSE=offline), the message currently displayed on the control
panel, and a status code. In the following example, the status code is
10001, which means the printer is ready. (See Appendix D for a list of
all printer status codes.)
Only the “string” portion of the “DISPLAY =” status message is
localized; the same message as that displayed on the control panel
appears in whichever language is used.
Note For those printers supporting Japanese printing, when the language
is set to Japanese, strings which correspond to a control panel
message are displayed on the control panel using the JIS X0201-76
character set.
Example: Using the INFO STATUS Command
This example requests status information. The printer, in this case a
HP LaserJet 4 printer, returns a status code (10001), the message
displayed on the control panel (00 READY), and the online status
(ONLINE=TRUE).
