Input and Output symbols in EAGLE (perhaps with Labels and XREF)
Just drag the output label over. It doesn't need to be touching the net at the label origin.



Note: To remove those little origin markers, use the set Option.ShowTextOrigins 0; command. Also note that this does not disconnect the label from the net, they are still associated (renaming the net will change the label). This simply moves the origin to not be on top of the net, so the two must be selected with the selection tool before being moved.
