the precision error obtaining module is used for acquiring the quality parameters of the code spraying product under the application scene element information and obtaining the printing precision error according to the quality parameters of the code spraying product;

the data matching module is used for constructing a jet printing precision error database, and matching the jet printing precision error with the jet printing precision error database to obtain a jet printing error matching type;

the data judging module is used for judging whether the jet printing error matching type is an inertia jet printing error or not, and obtaining an error judging result;

and the parameter adjustment module is used for adjusting control parameters of the ink jet printer based on the jet printing precision error if the error judgment result is the inertia jet printing error.
