1Productivity
If multiple intermediate-data generating schemes are used to optimize printing performance, then printing speed and efficiency are improved, but device complexity increases due to the need to predict and compare multiple schemes
Solution Approach 1:
The patent applies preliminary action by predicting the rasterizing time for each intermediate-data generating scheme before actual printing. The prediction unit calculates estimated processing times in advance, allowing the system to select the optimal scheme beforehand, thus avoiding actual trial-and-error during printing and improving overall printing speed.
Solution Approach 2:
The system applies self-service by using its own prediction capability to automatically select the best intermediate-data generating scheme without external intervention. The prediction unit and selection unit work together within the printer to autonomously determine the optimal processing path based on predicted performance metrics.
2Productivity
If the rasterizing time is predicted and optimized for each intermediate-data generating scheme, then printing efficiency is improved, but loss of time occurs due to the prediction and selection process itself
Solution Approach 1:
The patent applies partial action by predicting rasterizing times for only the necessary intermediate-data generating schemes rather than all possible schemes. The prediction unit focuses on calculating estimates for relevant schemes based on the specific print job characteristics, reducing unnecessary prediction overhead while still identifying the optimal scheme.
3Manufacturing precision
If the sheet conveying time is adjusted to match the predicted rasterizing time, then printing precision and quality are improved, but device complexity increases due to coordinated control requirements
Solution Approach 1:
The patent applies feedback by using the predicted rasterizing time to adjust the sheet conveying time. The control unit receives prediction results and automatically adjusts conveying parameters to ensure the sheet is ready at the optimal moment, creating a closed-loop system that improves printing quality through data-driven coordination.

AI summary
A printer includes an intermediate-data processor and an output-print-data generating unit. The intermediate-data processor performs a process in such a manner that intermediate data is generated from input print data. The output-print-data generating unit generates output print data from the intermediate data. The intermediate-data processor specifies one from intermediate-data generating schemes for a component of an object, on a basis of predicted generation performance of the output-print-data generating unit, and generates the intermediate data. The predicted generation performance is predicted for respective cases of generating the intermediate data by using the intermediate-data generating schemes.
