AI Technical Summary

Benefits of technology

This patent describes how to make sure documents are produced with good quality by comparing them against their original design without relying solely on any specific details about what they were supposed to look like beforehand.

Problems solved by technology

This patent describes various technical means for describing documents that require consistent attributes between each printer. However, current systems lack this attribute allow for efficient communication and management of image files. Additionally, existing systems provide no way to describe how these attributes relate to printers themselves.

Embodiment Construction

[0026] The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate embodiments and are not intended to limit the scope of the invention.

[0027]FIG. 1 illustrates a high level flow diagram for printing a document 105 based on a description in accordance with an aspect of the embodiments. After the start 101, a description is created that contains one or more image references 102. An image reference specifies a way to obtain an image from an image server. For example, the image reference can be a uniform resource locator for obtaining the image from a web server. The image reference can also be the name of a file stored on a network file server. The description is submitted to a printer and then parsed by the printer 103. Parsing is a general term used by those skilled in the art of computer programming for reading data and preparing to make use of it. By parsing the description, the printer discovers what image refer

Abstract

Descriptions can describe or contain document contents and layout. Some contents can be images and, instead of being included as image data in the description, can be image references. An image reference can be used to obtain an image, in the form of image data, from an image server. A printer can print the document after obtaining needed images from image servers. The image data often contains an image whose resolution does not match the resolution that the printer can properly print in the document. The image server can prepare image data with the correct resolution or can stream image data through a data connection to the printer in a hierarchical image format. A printer can receive a stream of hierarchically formatted image data until a desired resolution is reached and then simply close the data connection to cut off the stream of image data.
