I also wonder what will happen when I print file when the printer is offline, after I turn it on, will it be printed? What happens when I send job to printer while its offline, then I turn my computer off and I turn the printer on, will it be printed or not? Is there a way to disable (stop) p910nd print server when USB printer is turned off ( /dev/usb/lp0 doesnt exists)? Because I still see the printer as available in windows even if it’s turned off.
