An apparatus comprising:
- a print engine in a print zone;
- and
- a platen opposing the print engine to support print media, the platen including a plurality of openings in communication with at least one vacuum source;
- wherein
- the platen includes a non-vacuum region, comprising a surface devoid of openings in communication with the at least one vacuum source, the non-vacuum region underlying at least a portion of the print zone,
- wherein the print engine comprises a print head having an array of print dies, a row of dies being formed of the array of print dies,
- wherein the non-vacuum zone extends from a rearward edge of a forward row of dies to a rearward edge of a rearward row of dies.

A printer comprising:
- a print engine in a print zone;
- a platen opposing the print engine to support print media, the platen including a plurality of openings in communication with at least one vacuum source;
- and
- an airflow system to provide a flow of air through the print zone between the platen and the print engine;
- wherein
- the platen includes a non-vacuum region, comprising a surface devoid of openings in communication with the at least one vacuum source, the non-vacuum region being within the print zone to reduce local interaction between the vacuum and the flow of air from the airflow system,
- wherein the print engine comprises a print head having an array of print dies, a row of dies being formed of the array of print dies, and
- wherein the non-vacuum zone extends from a rearward edge of a forward row of dies to a rearward edge of a rearward row of dies.
