device.host_status

device.host_status

When this command is sent to the printer, the printer sends three data strings back. To avoid confusion, the host prints each string on a separate line.
This command is similar to the
~HS
 ZPL command.
The response for this SGD command does not include the
STX
 at the beginning of each data line and does not include the
ETX
 at the end of each data line as found in the
~HS
 response. Additionally, the first and second response lines for the SGD command contain a
CR/LF
 at the end of each line.
When the command is sent, the printer will not send a response to the host if the printer is in one of these conditions:
  • MEDIA OUT
  • RIBBON OUT
  • HEAD OPEN
  • REWINDER FULL
  • HEAD OVER-TEMPERATURE

Getvar

To return the current setting value:
! U1 getvar "device.host_status"
