A nozzle mount arrangement includes a substrate and a plurality of nozzle assemblies evenly distributed in a length direction of the substrate. The nozzle assembly includes a spray tongue connected to the substrate, a plurality of nozzles evenly distributed in a length direction of the spray tongue, and a locking mechanism provided on the spray tongue for pressing the spray tongue and the nozzle. An inkjet printer includes said nozzle mount arrangement. The nozzle mount arrangement and the inkjet printer have multiple nozzles on the spray tongue, thus the number of spray tongues is reduced, thereby reducing the assembly and maintenance costs of the spray tongues.
