ABSTRACT:
The present invention is a printer controller comprising a processor that exclusively executes a communication task for receiving packet data from host computers and extracting print job data on the basis of the received packet data, a language task for generating image data on the basis of the above-mentioned print job data, and a print task for controlling a print engine, according to priorities assigned to each of these tasks. The priorities assigned to the communication task and language task are altered according to specific conditions. For example, if the amount of packet data to be processed by the communication task is below a specific value, the priority of the language task is altered to be higher than the priority of the communication task, whereas if the amount of packet data to be processed by the communication task is over a specific value, the priority of the communication task is altered to be higher than the priority of the language task. Also, if the amount of print job data to be processed by the language task is below a specific value, the priority of the communication task is altered to be higher than the priority of the language task, whereas if the amount of print job data to be processed by the language task is over a specific value, the priority of the language task is altered to be higher than the priority of the communication task.
