Has anyone had issues with os x mavericks and pronterface? I have the screen saver and sleep turned off but the printer will stop if I leave the computer alone too long. I am printing from the USB cable but these issues are mavericks specific, os 10.8 was fine with this printer. Is it app nap?
I am not using pronterface, but I have had no trouble with printing with mavericks since setting standby to a suitably large number of hours.
That said, turning off app nap probably makes sense if you are having trouble. It seems easy enough to disable.
Let us know if it improves things.
