Claim 13:
14. A method, comprising:
loading a print medium onto a movable support surface of a media transport assembly of a printing system;
holding the print medium against the movable support surface via vacuum suction through platen holes and platen channels in a vacuum platen,
flowing air from a first region of a given platen channel of the platen channels through a second region of the given platen channel to one of the platen holes, an open cross-sectional area of the second region being reduced relative to the first region;
transporting the print medium, by moving the movable support surface relative to the vacuum platen, in a process direction through a deposition region of a printhead of the printing system; and
ejecting print fluid from the printhead to deposit the print fluid to the print medium in the deposition region,
wherein the second region of the given platen channel of the at least some platen channels comprises an obstruction feature located in the given platen channel, and
wherein the obstruction feature comprises one or more of a fin array, a pin array, a mesh, a porous material, a wall with an aperture, a baffle, or any combination thereof.
