I have an HP AIO 7250 printer through a Wi-fi home network for my new MBP. I also have a Dymo 450 label maker which is hooked into the Actiontec gateway with a usb cable. My problem is that I set the HP 7250 as the default printer and lock it in as the printer to use and default. However as soon as I go close out of preferences it always changes the on line printer to the Dymo label maker? Why can't I keep the HP as active even though it is the default printer and the preferences are locked? Any assistance is appreciated.
