Abstract
The invention provide a method for optimal use of print resource during the preparation a print job for printing. During the creation of a spool file, or similar intermediate file, the invention logs data on print resource usage in a print job in an accounting file. Upon review of this data, it modifies the print resource usage data in the accounting file as necessary to optimize print resource usage. The spool file and the accounting file are then sent to a printer driver. The printer driver knows how to use the print resource data in the accounting file to optimize the print resource usage.
Claims20
A method for preparing a print job for printing comprising the steps of:
- during creation of a spool file, logging data on print resource usage in a print job in an accounting file;
- modifying the print resource usage data in the accounting file to optimize print resource usage;
- sending the spool file and the accounting file to a printer driver;
- using the accounting file by the printer driver to create a print data stream wherein the using step further comprises:
- determining that a maximum number of print resources will have been downloaded at a first point in a print data stream to be sent to the printer;
- determining that a new print resource is required at a second point after the first point in the print data stream;
- determining a least used print resource after the second point by reference to the accounting file;
- and
- including commands to remove the least used print resource and install the new print resource at the second point.

A method for preparing a print job for printing comprising the steps of:
- receiving a spool file containing a print job and an accounting file containing print resource data in the print job by a printer driver;
- using the accounting file by the printer driver to improve print resource usage in the print job;
- and
- sending a print data stream to a printer wherein the using step further comprises:
- determining that a maximum number of print resources will have been downloaded at a first point in the optimized print data stream to be sent to the printer;

- determining a least used print resource after the second point by reference to the accounting file;
- and
- including commands to remove the least used print resource and install the new print resource at the second point.
