Printing apparatus and printing control method

A printing control method of controlling a printing apparatus, comprising:

• the first storage step of recording a history of a sub-scanning settling time of the printing apparatus in a memory;
• the second storage step of recording a history of a main scanning acceleration required time of the printing apparatus in a memory;
• the supposed settling time determination step of obtaining a supposed settling time in a next sub-scanning driving cycle on the basis of the history information of the sub-scanning settling time stored in the first storage step;
• the supposed idle time determination step of obtaining a supposed idle time from a next start of main scanning driving to a start of printing on the basis of the history information of the main scanning acceleration required time stored in the second storage step;
• the determination step of determining using the supposed settling time and the supposed idle time whether cross control in which main scanning driving starts before an end of sub-scanning driving can be executed in next print scanning processing;
• and
• the time difference determination step of determining a time difference from a start of sub-scanning driving to the start of main scanning driving using the supposed settling time and the supposed idle time on the basis of determination in the determination step in order to execute cross control in a next print scanning cycle.

A printing control program which causes a computer to function to control a printing apparatus, the program comprising:

• first storage means for recording a history of a sub-scanning settling time;
• second storage means for recording a history of a main scanning acceleration required time;
• supposed settling time determination means for obtaining a supposed settling time in a next sub-scanning driving cycle on the basis of the history information of the sub-scanning settling time stored in said first storage means;
• supposed idle time determination means for obtaining a supposed idle time from a next start of main scanning driving to a start of printing on the basis of the history information of the main scanning acceleration required time stored in said second storage means;
• determination means for determining using the supposed settling time and the supposed idle time whether cross control in which main scanning driving starts before an end of sub-scanning driving can be executed in next print scanning processing;
• and
• time difference determination means for determining a time difference from a start of sub-scanning driving to the start of main scanning driving using the supposed settling time and the supposed idle time on the basis of determination by said determination means in order to execute cross control in a next print scanning cycle.
