Client Apparatus Local Preview Generation for Wide-Width Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wide-width printing, the time required to display a preview image on a client apparatus is prolonged due to the high load of transferring large image data from a printing server via a network, degrading user convenience.
Innovation Solution
A client apparatus is configured with a converting unit to convert data into a printable format, an image generator to create a preview image based on the converted data, and a display unit to show the preview image, allowing it to rasterize data locally and avoid transferring drawing data from the printing server, thus enabling quick preview image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If preview image data are transferred from the printing server to the client apparatus via a network, then the user can check the preview image on the screen before printing, but a longer time is required for displaying the preview image due to high load for transferring large image data
Solution Approach 1:
The patent divides the preview image generation task into two parts: the printing server generates only a thumbnail preview image (small size) and transmits it to the client apparatus, while the client apparatus generates the full-size preview image locally using its own image generator. This segmentation reduces network transfer load and display time while maintaining user convenience.
Solution Approach 2:
The patent introduces a new functional dimension by equipping the client apparatus with an image generator capability, transforming it from a passive display device to an active image processing device. This dimensional change allows the client to handle large image data locally, eliminating the bottleneck of network transfer for large files.
2Area of stationary object
If wide-width printing is performed with large amount of image data, then the printing quality and coverage are improved, but the drawing process time and network transfer time are prolonged
Solution Approach 1:
The patent applies partial action by having the printing server generate only a thumbnail preview image instead of the full-size wide-width image. This partial generation satisfies the immediate need for preview display without incurring the full time cost of processing and transferring the complete large-size image data.
Solution Approach 2:
The client apparatus performs self-service by generating its own full-size preview image locally using its embedded image generator. This eliminates the need for the server to perform the time-consuming full image generation and transfer, allowing the client to serve itself with the complete preview data.

AI summary
Disclosed is a client apparatus connected to a printing server and configured to instruct the printing server to execute printing. The client apparatus includes a converting unit configured to convert a format of data to be printed into a printable format, an image generator configured to generate a preview image of the data to be printed adapted to a printing condition based on the data of the converted format, and a display unit configured to display the preview image.
