A portable communication terminal causes an image forming apparatus to print. The portable communication terminal includes a terminal storage unit, an operation unit, a processing unit, and a terminal communication. The processing unit calculates a first required time and a second required time. The first required time is a time spent when the image forming apparatus performs a predetermined image processing on the generated print job data. The second required time is a time spent when the portable communication terminal performs the predetermined image processing on the generated print job data. When the first required time is equal to or less than the second required time, the processing unit causes the image forming apparatus to perform the predetermined image processing. When the first required time is longer than the second required time, the processing unit performs the predetermined image processing on the print job data. |

1. A portable communication terminal for causing an image forming apparatus to print, the portable communication terminal comprising:
a terminal storage unit that stores data for a target of a print job; an operation unit that accepts an execution instruction of the print job based on the data stored in the terminal storage unit; a processing unit that generates print job data to execute the print job based on the data stored in the terminal storage unit when the execution is instructed, so as to perform image processing on the print job data; and a terminal communication unit that transmits the print job data to the image forming apparatus and communicates with the image forming apparatus; wherein the terminal storage unit stores
a device-side throughput as a data amount processable by image processing per unit time in the image forming apparatus,a terminal-side throughput as a data amount processable by image processing per unit time in the portable communication terminal, anda return time since the image forming apparatus returns from a power-saving mode until the image forming apparatus becomes a state that enables starting image processing, the power-saving mode stopping power supply to a portion that performs the image processing in the image forming apparatus; and the processing unit
recognizes a size of the generated print job data,causes the terminal communication unit to check whether the image forming apparatus to which the print job data is transmitted is in the power-saving mode or not,calculates a first required time and a second required time, the first required time being a time spent when the image forming apparatus performs a predetermined image processing on the generated print job data, the second required time being a time spent when the portable communication terminal performs the predetermined image processing on the generated print job data, the first required time being calculated based on a time obtained by adding the return time to a value obtained by dividing a data size of the print job data by the device-side throughput when the image forming apparatus is in the power-saving mode and calculated based on a value obtained by dividing the data size of the print job data by the device-side throughput when the image forming apparatus is not in the power-saving mode, the second required time being calculated based on a value obtained by dividing the data size of the print job data by the terminal-side throughput,when the first required time is equal to or less than the second required time, the processing unit causes the terminal communication unit to transmit the print job data before the predetermined image processing to the image forming apparatus and causes the image forming apparatus to perform the predetermined image processing, andwhen the first required time is longer than the second required time, the processing unit performs the predetermined image processing on the print job data and causes the terminal communication unit to transmit the print job data after the predetermined image processing to the image forming apparatus. |
