Issue / Question

Printer switching off when USB cable or charger is disconnected.

Applicable To

Zebra mobile printers excluding ZQ600 Series, ZQ110

Resolution / Answer

By default the "power.dtr_power_off" is set to ''on''. This is causing the printer to switch off.

To disable this option the command below should be sent

! U1 setvar "power.dtr_power_off" "off"

This command refers to the remote printer power control, and is used for power management.

  • When Data Terminal Ready (DTR) is enabled the printer can be powered on and off via the Data Set Ready (DSR) signal.
  • When DTR power off is enabled, a low to high transition will cause the printer to turn ON and a high to low transition will cause the printer to turn OFF.
