Print Control Apparatus Paper Type Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in selecting the correct paper type for printing, especially in large-format printers, where multiple paper types are supported, leading to paper type mismatches and inefficient ink usage due to the need for manual search and selection from a list.
Innovation Solution
A print controlling apparatus and method that prioritizes the display of the paper type from the latest suspended job in the print job queue during paper replacement, allowing users to easily select the appropriate paper type, thereby reducing the burden of selecting from multiple options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user selects paper type from a list of multiple paper types, then the correct paper type can be selected, but the user burden increases due to manual search and selection
Solution Approach 1:
The system performs preliminary action by automatically acquiring the paper attribute from the suspended job before the user needs to select. The acquisition unit retrieves the paper type information in advance, so when the user views the selection screen, the correct paper type is already prepared and highlighted, eliminating the need for manual search.
Solution Approach 2:
The system provides self-service by automatically determining and highlighting the appropriate paper type based on the suspended job's requirements. The display controlling unit automatically presents the correct paper attribute as the first candidate, allowing the user to simply confirm rather than manually search through multiple options.
2Ease of operation
If the paper type from suspended job is prioritized in display, then user selection is simplified, but the system complexity increases
Solution Approach 1:
The system segments the paper type selection process into distinct functional components: the acquisition unit separately retrieves paper attribute information from suspended jobs, the display controlling unit separately handles the presentation and highlighting logic, and the print controlling unit separately manages the actual printing. This segmentation allows each component to be simple and focused, reducing overall system complexity.
Solution Approach 2:
The acquisition unit performs preliminary action by pre-acquiring paper attribute information from suspended jobs before the user needs to make a selection. This pre-processing eliminates the need for complex real-time calculations or searches during the user interaction, simplifying the display controlling unit's task to merely presenting pre-fetched information.

AI summary
A paper attribute designated by a suspended job which has been stored in a print job queue and printing of which has not been executed is acquired. When executing replacement of paper supplied to the printing apparatus is executed, a screen in which a user can designate a paper attribute candidate after paper replacement is displayed so that the acquired paper attribute is preferentially displayed out of candidates which the user can select as the paper attribute candidate. An image is printed on printing paper after the replacement, based on a paper attribute designated by the user in the screen.
