Function: build550Recovery()
build550Recovery():
Uint8Array
550 recovery sequence — ESC Q to release any pending job state and the host print lock. Soft path; safe to send at any time.
For a hard recovery (ESC @ reboot), use build550Restart() separately — it will lose any buffered data and is documented as destructive.
Returns
Uint8Array
