Method and structure for sealing fine fluid features in a printing device

An ink jet printer, comprising:

• at least one ink jet printhead, comprising:
• a substrate comprising an ink channel configured to pass ink through the substrate;
• a first adhesive that attaches a printing device comprising at least one fluid path to the substrate, wherein the first adhesive is interposed the printing device and the substrate;
• and
• a second adhesive having a chemical composition different than a chemical composition of the first adhesive that further attaches the printing device to the substrate, wherein the second adhesive physically contacts an edge of the printing device and the substrate and seals a gap from the ink channel to a location between the printing device and the substrate;
• and
• a printer housing that encases the at least one printhead.
