Image forming apparatus, print control method, and computer-readable recording medium storing print control program

A print control method for reading data stored in an external storage device and printing the data using an image forming apparatus having an interface for connecting the external storage device with the image forming apparatus, the method comprising:

• an acquiring step of acquiring, from information about data stored in the storage device, a parameter for calculating a memory usage at a time of printing the data;
• a retaining step of retaining a coefficient value for the calculation of the memory usage, in association with each file type, the coefficient value characterizing the memory usage during printing on a per-page basis for a file type;
• a calculating step of calculating the memory usage by acquiring the coefficient value associated with the file type for calculating the memory usage, based on information indicating the file type of the parameter acquired by the acquisition unit, and then substituting the acquired coefficient value for calculating the memory usage into a set calculating formula;
• and
• a control step of comparing the memory usage calculated in the calculating step with a memory capacity available in the image forming apparatus during printing, and controlling an image forming operation during printing based on a comparison result.

A non-transitory computer-readable recording medium storing a print control program for reading data stored in an external storage device and printing the data using an image forming apparatus having an interface for connecting the external storage device with the image forming apparatus,

• wherein execution of a computer-readable program by one or more processors of an information processing apparatus causes the one or more processors to perform:
• an acquiring step of acquiring, from information about data stored in the storage device, a parameter for calculating a memory usage at a time of printing the data;
• a retaining step of retaining a coefficient value for the calculation of the memory usage, in association with each file type, the coefficient value characterizing the memory usage during printing on a per-page basis for a file type;
• a calculating step of calculating the memory usage by acquiring the coefficient value associated with the file type for calculating the memory usage, based on information indicating the file type of the parameter acquired by the acquisition unit, and then substituting the acquired coefficient value for calculating the memory usage into a set calculating formula;
• and
• a control step of comparing the memory usage calculated in the calculating step with a memory capacity available in the image forming apparatus during printing, and controlling an image forming operation during printing based on a comparison result.
