I have this problem that sometimes my printer doesn't work. I think it happens after my macbook has been hibernating (I'm not a 100 percent sure about this, I'll test it). It won't work again until I restart my macbook. This is the error message I get: fatal: Opening Printer Connection Failed: Unable to open the printer connection. Please check your printer connections and check for printer errors. Any idea what this could be a about? The printer is a hp psc 1210.
