The methods and apparatuses herein relate to inkjet printing a substrate at a desired print resolution. A substrate advances at a first speed under the first printhead and the second printhead such that a desired print resolution exceeds the maximum print resolutions of a first printhead and a second printhead. When the substrate is advancing at the first speed, the first printhead ejects ink onto the advancing substrate at a first firing frequency to create a first printed zone, and the second printhead ejects ink onto the advancing substrate at a second firing frequency to create a second printed zone. In turn, the first printed zone and the second zone together define a printed region having the desired print resolution.
