Print Rotation Feedback for Layout Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems using generic printer drivers and cloud printing services face limitations in extending print settings, leading to unintended output layouts and rotations, especially in N-in-1 printing, due to the lack of communication with the printer about image rotations performed during PDL conversion.
Innovation Solution
A control method implemented in an information processing apparatus that acquires capability information from a printer, determines whether to allow image rotation based on this information, and provides this determination to the operating system, ensuring that the printer is notified of any image rotations and can perform printing accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the PDL conversion function automatically rotates images based on sheet feed direction, then printing efficiency is improved, but the printer is not notified of the rotation causing unintended output layouts
Solution Approach 1:
The patent implements a feedback mechanism where the information processing apparatus notifies the printer of image rotations that occurred during PDL conversion. The notification includes rotation angle and direction information, allowing the printer to adjust its processing accordingly. This resolves the information loss while maintaining the automatic rotation efficiency benefit.
Solution Approach 2:
The system performs preliminary action by notifying the printer in advance about the image rotation that will occur during printing. This allows the printer to pre-prepare for the rotation, ensuring correct output layout while maintaining the automatic conversion efficiency.
2Adaptability or versatility
If generic printer drivers are used to support multiple printer vendors, then versatility is improved, but print setting extension capabilities are limited
Solution Approach 1:
The patent introduces an intermediary mechanism between the generic printer driver and the printer. This intermediary handles the communication of rotation information and other extended settings from the information processing apparatus to the printer, allowing the generic driver to maintain versatility while enabling extended print settings through the intermediary layer.
3Shape
If image rotation is performed during PDL conversion, then printing orientation is improved, but post-processing positions become incorrect
Solution Approach 1:
The patent uses feedback to communicate the rotation information from the PDL conversion process to the printer. The printer receives notification about the rotation angle and direction, allowing it to correctly position post-processing operations such as stapling or punching relative to the rotated image, thus maintaining precision despite the rotation.
