Abstract

A technique is described whereby resource loading of print information, as used in advanced function printers, is optimized by means of a merging operation. By merging the file information, the speed of printing complex documents can be improved. The concept also provides additional information which can be used to reduce the size of font resources, so as to improve the printing speed and to enhance the complexity of documents to be processed. The utilization of the concepts merging of resource loading information file produces a new resource loading information file format for print service facilities [*]. Added to each resource section of the record is the page number, to be used when each resource will be required.

Optimizing Resource Loading for Advanced Function Printers

A technique is described whereby resource loading of print information, as used in advanced function printers, is optimized by means of a merging operation. By merging the file information, the speed of printing complex documents can be improved. The concept also provides additional information which can be used to reduce the size of font resources, so as to improve the printing speed and to enhance the complexity of documents to be processed. The utilization of the concepts merging of resource loading information file produces a new resource loading information file format for print service facilities [*]. Added to each resource section of the record is the page number, to be used when each resource will be required. The resource loading information file is read from bottom to top and each record's resource information is merged with the previous record's resource information in page order. When the merge is completed, the top record contains all of the resources needed to print the entire data set. The rest of the page records in the file contain the resources required to print the print data set from that page until the end. An example of the merged resource loading information record is shown in Fig. 1. Using this information, the device dependent print driver can preload resources, depending on the operating parameters such as storage restrictions, maximum number of fonts, page segments, etc. When new resources need to loaded into the printer, the print driver can determine which previously loaded resources can be deleted with the least impact. The merging process and the use of this informat...
