The printing tasks with the same terminal identification and printer identification are combined by setting the time range, so that the printing tasks within too long time are prevented from being combined, and the printing efficiency of the printing tasks corresponding to other terminal identifications is reduced.
In one embodiment, the print job also carries the terminal location.

And configuring a corresponding distance weight value for the distance, configuring a corresponding time weight value for the receiving time, acquiring the sum of the distance weight value and the time weight value, and sequencing the printing tasks with the same printer identification according to the descending or descending of the sum of the distance weight values. The larger the distance is, the larger the corresponding distance weight value is, the earlier the receiving time is, and the larger the corresponding time weight value is. Therefore, the printing tasks with large distance and early receiving time are sequenced at the top, and the printing efficiency of the printing tasks is improved.
