Public bug reported:

SETUP:
I have hplip and cups on a "server" machine sharing a USB printer over LAN.

OBSERVED:
If the printer is off / and a remote machine sends a print request, CUPS/HPlip will accept the request and silently stop the printer.  Even if the printer is subsequently turned on, the server will accept and enqueue the job but not print since printer is "stopped"
The only way to recover is for an admin to log in and restart the printer from HPlip-gui (Printer / Queue control).

FIX:
I see one of two possibilities:
1. If printer is not ON then HPLip / CUPS should reject incoming jobs outright.
2. If job is accepted and enqueued then HPLip should start printing as soon as printer becomes available.

Not sure if 
- this behaviour is because of CUPS or HPLIP or both?
- this behavious is intended and by design?
