49results about How to "Flexible printing" patented technology

A context-aware printing method and system invoke contextual rendering tags to realize more flexible printing. The contextual rendering tags provide information about the nature or purpose of print elements in a document and are used to identify and selectively modify print elements in a given print instance of the document at the discretion of the user. The contextual rendering tags provide added flexibility in printing by enabling a user to make a broad array of purpose-driven modifications and enabling a document to be printed in multiple instances and in any sequence with modifications indicated by all contextual rendering tags, modifications indicated by a subset of contextual rendering tags or no context-based modifications. For example, print elements that are designated nonessential by contextual rendering tags can be excluded from a printed document in a first print instance to reduce ink consumption and included in a printed document in a second print instance where an unaltered document is required.
