Hello Muskrat44.
I understand your concerns with your Deskjet 4580 software having conflicts. Could you elaborate further on what happens when your software conflicts?
Are you unable to print and scan when this happens?
How are you connecting this printer; wireless or USB?
In this thread you stated that your Deskjet is interfering with Internet Explorer. Are you unable to use Internet Explorer once you have the printer installed?
Once I have verify this information I can assist you further.
