Method of correcting print data and system of editing and printing documents

A print data correcting method in a document editing and printing system in which a document is edited by a data processor with a display, a result of editing is output as a print job containing document data which is to be printed from said data processor to a printer, and said document data of said print job is printed by said printer, comprising the steps of:

• inputting and editing said document data by an operation of said data processor by a user;
• outputting inputted and edited said document data from said data processor to said printer as an invoked print job and causing said printer to start to print said document data of said invoked print job;
• storing in said data processor control data indicative of printed document data portions of said invoked print job which are already printed and waiting document data portions of said invoked print job which are print-waiting;
• displaying said printed document data portions which are already printed and said waiting document data portions which are print-waiting on said display;
• allowing said user to operate said data processor to correct said printed document data portions of said invoked print job and said waiting document data portions of said invoked print job;
• and
• only when said waiting document data portions are corrected, sequentially outputting corrected document data as corrected document data portions for said invoked print job, and when said printed document data portions are corrected, outputting corrected document data as further corrected document data portions of said invoked print job corresponding to a page of said document data which has been corrected;
• and
• causing said printer to continue to print said document data of said invoked print job, including said corrected document data portions such that a printed document data from said invoked print job incorporates said corrected document data.

A document editing and printing system for printing a print job while allowing editing of said print job during a printing operation, said system comprising:

• a storage means having at least a storage region for storing an invoked print job having document data in document data blocks of a specified size, and a first identifier for each respective document data block indicative of whether said respective document data block has been printed or is print-waiting;
• an inputting means for allowing a user to input document data into said system;
• a displaying means for displaying said document data of said invoked print job;
• a printing means for printing said document data of said invoked print job;
• and
• a central processing unit including:
• an edit means for editing document data of said invoked print job on a basis of input from said inputting means and storing edited document data into said storage means for said invoked print job;
• a print control means, receiving said document data blocks of edited document data from said storage means, for sending said document data blocks of said edited document data for said invoked print job to said printing means, and setting said first identifier with respect to sent said document data blocks to indicate said sent document data blocks of said invoked print job as having been printed;
• and
• an edit control means for displaying at least print-waiting document data of said invoked print job according to said first identifiers and storing said edited document data of said invoked print job in said storage means after correcting said document data;
• wherein said system causes said printing means to print said document data of said invoked print job, including corrected document data portions such that a printed document data from said invoked print job incorporates said corrected document data.

A document editing and printing system for printing a print job while allowing editing of said print job during a printing operation, said system comprising:

• a storage means having at least a storage region for storing document data of an invoked print job in document data blocks of a specified size, and a first identifier for each respective document data block indicative of whether said respective document data block has been printed or is print-waiting;
• identifier means for setting said first identifiers according to whether said document data of said document data blocks are already printed or print-waiting, and third identifiers according to whether reprinting of corresponding document data portions of said invoked print job is required or not;
• an inputting means for allowing a user to input document data into said system;
• a displaying means for displaying said document data;
• a printing means for printing said document data of said invoked print job;
• and
• a central processing unit including:
• an edit means for editing document data on a basis of input from said inputting means and storing edited document data into said storage means;
• a print control means, receiving said document data blocks of said edited document data from said storage means, for sending said document data blocks of said edited document data of said invoked print job to said printing means, and setting said first identifier with respect to sent said document data blocks to indicate said sent document data blocks of said invoked print job as having been printed;
• an edit control means for displaying document data including print-waiting document data and printed document data of said invoked print job distinctively according to said first identifiers and storing said edited document data of said invoked print job in said storage means after correcting said document data, and for setting said third identifiers indicative of said document data of said invoked print job needing reprinting when printed document data are corrected;
• and
• a print monitor means for monitoring said third identifiers periodically, and driving said print control means to reprint said corrected document data when said third identifiers indicates a need of reprinting;
• wherein said system causes said printing means to print said document data of said invoked print job, including corrected document data portions such that a printed document data from said invoked print job incorporates said corrected document data.
