Dual substrate processing

An inkjet printer, comprising:

• a substrate support having a gas floatation system to provide a gas cushion, the substrate support comprising a processing zone having suction openings to control a pressure of the gas cushion in the processing zone, the suction openings being arranged in two groups that define a central gap in the processing zone;
• a print support extending across the substrate support at the processing zone and supporting a printhead assembly for dispensing material onto a substrate supported on the substrate support in the processing zone;
• a first substrate holder on a first side of the substrate support adjacent to a first substrate location on the substrate support to move a first substrate along the substrate support;
• and
• a second substrate holder on a second side of the substrate support opposite from the first substrate holder and adjacent to a second substrate location on the substrate support to move a second substrate along the substrate support.

A processing system, comprising:

• a processing section, comprising:
• a dual-substrate inkjet printing chamber;
• a dual-substrate processing chamber;
• and
• a transfer chamber coupling the dual-substrate inkjet printing chamber and the dual-substrate processing chamber;
• and
• a dual-substrate interface chamber coupled to the processing section to provide two substrates in side-by-side arrangement for processing in the processing section.
