a print control method and device , wherein the method includes : monitoring a print system port , storing a print task at a preset memory address in the form of job file when the print task exists at the print system port ; querying the memory address on schedule , determining the target job file when there is a job file storing at the memory address ; querying the printer state , if the printer is idle , sending the target job file ; when the printer is in a state of failure , feeding a failure state prompting information back . the solution queries the printer work state before the job file is sent , feeds the prompting information back when the printer occurs failure , detects the print process state of job files , and performs a processing for failure when a print fails . through the solution , users can know the states of job files in time and missing or omitting of a job file is avoided .
