Abstract
In a printer control device, the number of printing sheets required for processing printing requests are detected, and when it is determined that the required number of printing sheets of a printing request is larger than a predetermined value, the order for printing is changed such that the printing request is processed later. Therefore, the problem is eliminated wherein a relatively short printing request is not processed for an extremely long period of time.
Claims7
A printer control device having means for reading originals of documents to be printed and which receives printing request to print out corresponding documents in a predetermined order, the length of each document being obtained by converting the heights of originals of document stacked on an original tray into a number of document pages, said device comprising:
- means for storing said printing requests;
- detecting means for detecting the number of printing sheets required for processing said printing requests;
- means for determining whether the required number of printing sheets of a printing request is greater than a predetermined value;
- and
- means for changing said predetermined order for printing by moving the printing requests having a required number of printing sheets greater than said predetermined value to the end of new order of priority.
A printer control device which receives printing requests to print out corresponding documents in a predetermined order, comprising:
- means for storing said printing request;
- detecting means for detecting the number of printing sheets required for processing said printing requests;
- means for determining whether the required number of printing sheets of a printing request is greater than a predetermined value;
- and
- means for changing said predetermined order for printing requests which are received during a predetermined time interval by moving the printing requests having a required number of printing sheets greater than said predetermined value to the end of a new order for printing.
A printer control device which receives printing requests to print out corresponding documents in a predetermined order, comprising:
- means for storing said printing requests;
- detecting means for detecting the number of printing sheets required for processing said printing requests;
- means for determining whether the required number of printing sheets of a printing request is greater than a predetermined value;
- and
- means for changing said predetermined order for printing every time a predetermined number of printing requests are received by moving the printing requests having a required number of printing sheets greater than said predetermined value to the end of a new order for printing.
A printer control device which receives printing requests to print out corresponding documents in a predetermined order, comprising:
- means for storing said printing requests;
- detecting means for detecting the number of printing sheets required for processing said printing requests;
- means for determining whether the required number of printing sheets of a printing request is greater than a predetermined value;
- means for changing said predetermined order of priority by moving the printing requests having a required number of printing sheets greater than said predetermined value to the end of a new order for printing;
- and
- flag setting means for preventing a printing request from being moved to the end of said order for printing more than once.
A printer control device which receives printing requests to print out corresponding documents in a predetermined order, comprising:
- means for storing said printing requests;
- detecting means for detecting the number of printing sheets required for processing said printing requests;
- means for determining whether the required number of printing sheets of a printing request is greater than a predetermined value;
- means for changing said predetermined order of priority by moving the printing requests having a required number of printing sheets greater than said predetermined value to the end of a new order for printing;
- and
- flag setting means for preventing a printing request from being moved to the end of the order for printing under at least a predetermined condition.
