To return the state of the system error flags:

Example
This example shows how to request the printer’s status.
To request the printer’s status, type
! U1 getvar "zpl.system_error"
The printer responds with data similar to this:
"1,1,00000000,00000004"
In this example, the Printer Status resolves to these conditions:
  • The printer is in Pause (value = 1)
  • The Error Flag is 0 if there are no errors (i.e. Group 2 and Group 1 are all 0s), and 1 if there are any errors.
  • The cover/printhead is open (value = 4).
