Information processing apparatus and its control method

An information processing apparatus, which simulates a behavior of a sheet-like printing medium having a flexibility when the printing medium is conveyed in a conveying path including a convey roller pair, comprising:

• setting means for setting a condition including a position of the convey roller pair arranged in the conveying path;
• drive condition setting means for setting a drive condition indicating a time-series drive velocity of the convey roller pair;
• calculation time adjustment means for, when a time of a drive velocity change point in the drive condition does not match a calculation time, matching the calculation time with the time of the drive velocity change point;
• and
• simulation means for simulating the behavior of the printing medium when the printing medium is conveyed in the conveying path on the basis of the condition set by said setting means, the drive condition, and the matched calculation time.

A method of controlling an information processing apparatus, which simulates a behavior of a sheet-like printing medium having a flexibility when the printing medium is conveyed in a conveying path including a convey roller pair, comprising:

• a setting step of setting a condition including an information associated with a rigidity of the convey roller pair arranged in the conveying path;
• a nip shape formation step of forming a shape of a contact area where the convey roller pair contact each other on the basis of the set condition;
• and
• a simulation step of simulating the behavior of the printing medium when the printing medium is conveyed in the conveying path on the basis of the shape of the contact area.
