The invention relates to a printing control method and a printing device for a gas sensor array. The method at least comprises the following steps: determining the modulation range of surface tension and viscosity of conductive ink based on the aperture of a spray head, the density of the conductive ink to be modulated and a printing stability parameter Z, wherein the range of Z is 1-12; under the condition that the surface tension and the viscosity of the conductive ink reach corresponding modulation ranges, finely adjusting pulse voltage change parameters based on a preset nozzle voltage pulse sequence diagram so as to control droplet jetting parameters, and printing the conductive ink on a sensor array substrate according to a preset interval and forming an interdigital electrode pattern; and printing the optimized metal oxide particle suspension on the corresponding interdigital electrode pattern to form the gas-sensitive film. The gas sensor array obtained by printing through the prepared conductive ink
