Link order
When linking more than one GPO to an OU, there could be a problem when two or more GPOs have the same settings but with opposite configuration, like, GPO1 have Allow printer installation among other settings but GPO2 is configured to prevent printer installation among other settings. Because the two GPOs are at the same level, there is a link order which can be changed.
The GPO with the lowest link order is processed last, and therefore has the highest precedence
