Printing Control Apparatus Omitting Redundant Reuse Part Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printing systems, despite using parallel RIP processing and caching, do not adequately increase the speed of the entire printing process due to unnecessary transmission of reuse parts for each page.
Innovation Solution
A printing control apparatus that stores and identifies reuse parts with unique identifiers, omitting the transmission of reuse parts already sent to the printer, and uses multiple output processing units to enhance data conversion speed, while also caching RIP-processed data for efficient retransmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reuse parts are transmitted for each page using parallel RIP processing and caching, then the RIP process speed is increased, but the overall printing process speed is not sufficiently increased due to redundant data transmission
Solution Approach 1:
The patent extracts reuse part data from the normal transmission flow and stores it separately in a reuse part data storage unit. By identifying and separating reusable content (headers, footers, standard clauses) from unique page content, the system prevents redundant transmission of identical data across multiple pages, thereby reducing overall printing process time while maintaining RIP processing efficiency
Solution Approach 2:
The patent performs preliminary identification and storage of reuse parts before the actual printing process. By pre-processing manuscript data to identify reusable sections and storing them in advance, the system eliminates the need for repeated transmission of identical data, thus reducing total printing time without compromising the speed of the RIP process itself
2Reliability
If all manuscript data is transmitted to the printer for each page, then complete printing output is achieved, but transmission time increases due to redundant reuse part data
Solution Approach 1:
The patent segments manuscript data into distinct components: reuse parts (headers, footers, standard clauses) and unique page content. By dividing the data transmission into these segments and handling them differently (storing reuse parts separately, transmitting only unique content), the system maintains complete printing output while significantly reducing redundant data transmission time
Solution Approach 2:
The patent introduces a reuse part data storage unit as an intermediary between the RIP processing and the printer. This intermediary stores reusable data segments and provides them to the printer without requiring repeated transmission from the source, thus ensuring complete printing output while minimizing transmission time

AI summary
A first RIP processing unit reads cache data from a first cache unit. The first RIP processing unit transmits first RIP-processed variable part data to a printer. Since an identifier read by the first RIP processing unit is not a transmitted identifier, the first RIP processing unit transmits RIP-processed reuse part data to the printer. A second RIP processing unit reads cache data from a second cache unit. The second RIP processing unit transmits second RIP-processed variable part data to the printer. Since an identifier read by the second RIP processing unit is a transmitted identifier, the second RIP processing unit does not transmit the RIP-processed reuse part data to the printer.
