A method for generating print parameters includes: obtaining a printed paper of a test sample sheet obtained by a printing device after performing double-sided printing on the test sample sheet using preset front print parameters and preset back print parameters; detecting a front effect index of a front print effect and a back effect index of a back print effect for the printed paper of the test sample sheet by a print parameter generating device; comparing the front effect index and the back effect index with a standard effect index to obtain a comparison result, or comparing the front effect index with the back effect index to obtain a comparison result; determining from the comparison result and store in the printing device front print parameters and back print parameters used for double-sided printing on a paper to be printed with the same material and attributes as the test sample sheet.
