Gas bearing systems, print gap control systems, and methods of print gap control are provided. The gas bearing systems can accommodate one or more print module packages. The systems and methods can be used for inkjet and/or thermal printing applications such as manufacturing organic light emitting devices (OLEDs). Gas bearing systems can employ one or more of pressurized gas and vacuum. For oxygen-sensitive applications, an inert gas, such as nitrogen gas, can be employed as the pressurized gas. Fluid channels and apertures of the gas bearing systems can be varied in terms of size and relative position to one another. Fluid channels and apertures can be grouped and paired with one or more manifolds and ultimately a pressurized gas and/or vacuum source.
