how do I change my printer's name in sidebar under shared devices?
My printer was shown in the sidebar as a number - it was found by my Mac from the router which had the printer attached to my old PC
Now that I have downloaded the software for this printer it works fine but has this funny number as a secondary name and I wish to rename it.
There is also another funny code which I have not identified as to which device that is , probably the screen of my old PC as I have turned of the PC but not yet disconnected the screen from it.
iMac (21.5-inch, Mid 2014), OS X Yosemite (10.10.1)
