Data processing apparatus, data processing method, program, and ink jet printing system

A data processing apparatus for supplying data to an ink jet printing apparatus, wherein the ink jet printing apparatus can perform a marginless printing for printing without providing margin on an edge of the print medium by ejecting ink onto an area inside the edge of the print medium and onto an overrunning area outside the edge based on recording data, the data processing apparatus comprising:

• obtaining means for obtaining a value equivalent to a waste ink volume associated with the marginless printing;
• and
• data sending means for sending data representing the value obtained by said obtaining means to the ink jet printing apparatus,
• wherein said obtaining means obtains the value by counting a number of ink droplets to be ejected onto the overrunning area based on the recording data.

A program for controlling an ink jet printing apparatus, wherein the ink jet printing apparatus can perform a marginless printing for printing without providing margin on an edge of the print medium by ejecting ink onto an area inside the edge of the print medium and onto an overrunning area outside the edge based on recording data, the program causing a computer to execute steps of:

• obtaining a value equivalent to a waste ink volume associated with the marginless printing;
• and
• sending data representing the obtained value to the ink jet printing apparatus,
• wherein the value is obtained by counting a number of ink ejections to the overrunning area based on the recording data.

An ink jet printing system having an ink jet printing apparatus and a host for supplying print data to the ink jet printing apparatus, wherein the ink jet printing apparatus can perform a marginless printing for printing without providing margin on an edge of the print medium by ejecting ink onto an area inside the edge of the print medium and onto an overrunning area outside the edge based on recording data,

• the host comprising:
• waste ink volume obtaining means for obtaining a value equivalent to a waste ink volume associated with the marginless printing, the value being obtained by counting a number of ink droplets to be ejected onto the overrunning area based on the recording data;
• and
• data sending means for sending data representing the value obtained by said waste ink volume obtaining means to the ink jet printing apparatus;
• the ink jet printing apparatus comprising:
• an ink receiving member for receiving waste ink ejected onto the overrunning area during the marginless printing;
• and
• an accumulated value memory means for cumulatively adding up the value of data sent from the host and storing an accumulated value equivalent to waste ink volumes ejected onto the ink receiving member.
