WiFiLabel~JR: Power On Reset (ZPL)
Restarts the printer as if power had been cycled.
Power-on reset reboots the printer. Jobs in the buffer are dropped and the mechanism restarts its power-up sequence. Use it when a save or a language change will not take effect until the next boot. Do not send it in the middle of a batch you still need. The library treats it as destructive and requires confirm. The printer will be quiet on USB for a few seconds and may renumber or re-enumerate. Wait until the head is ready, then query identification before sending another format.
