Printer Control Unit Continuous Feed Without Large Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printer control systems are limited in their ability to perform continuous feed control across multiple print jobs, especially in scenarios where printers have limited memory capacity.
Innovation Solution
A printing apparatus equipped with one or more processors and circuitry that includes a reception unit for receiving print jobs with setting information and a control unit capable of performing continuous printing processes based on the setting information of multiple print jobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous feed control is implemented across multiple print jobs, then productivity is improved, but memory capacity requirements increase
Solution Approach 1:
The patent extracts only the necessary setting information from print jobs rather than storing complete job data. The control unit receives and processes setting information (such as paper size, print quality, color settings) separately from the actual print data, allowing continuous feed control to be implemented without requiring large memory capacity to store entire print jobs.
Solution Approach 2:
The patent segments the print job processing into separate components: setting information reception, setting information storage, and actual printing execution. By dividing the print job into these segments, the system can maintain setting information for multiple jobs in memory while processing them sequentially, enabling continuous feed control without needing to store all job data simultaneously.
2Productivity
If setting information of multiple print jobs is stored simultaneously, then continuous feed control across jobs is enabled, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by receiving and storing setting information for the next print job before the current job is completely processed. The control unit prepares the setting information in advance, so when the current job finishes, the next job can immediately proceed without interruption, enabling continuous feed control while keeping the control logic relatively simple.
3Ease of operation
If the printer waits for complete print job data before receiving next job settings, then data management is simplified, but productivity decreases
Solution Approach 1:
The patent applies preliminary action by receiving setting information for subsequent print jobs in advance, before the current job's data processing is complete. This allows the printer to prepare for the next job while the current job is still being processed, eliminating idle time and improving productivity without significantly complicating data management.

AI summary
A printing apparatus includes: one or more processors and/or circuitry which function as: a reception unit configured to receive print jobs including setting information and job data, and being capable of receiving the setting information of at least one second print job while a first print job is executed, the second print job being different from the first print job; and a control unit configured to perform a continuous printing process on the second print job based on the setting information of the first print job and the received setting information of the second print job.
