Mobile Terminal Pull Printing via Computing Device Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for printing content from a PC to a mobile device are complex and degrade printing quality, and traditional pull printing requires a server, incurring additional costs for its maintenance and operation.
Innovation Solution
A computing device and system that utilize a mobile terminal to perform pull printing by searching for available mobile terminals, rendering print data into a printable format, and transmitting it to the selected mobile terminal, which then sends the data to a printer, eliminating the need for a server and improving printing quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is transmitted to mobile terminal via USB cable or email or cloud server for printing, then printing functionality is achieved, but the process becomes complicated and printing quality degrades
Solution Approach 1:
The patent introduces a server as an intermediary component that stores print data and manages the printing process. The computing device sends print data to the server, which then transmits it to the mobile terminal for printing. This intermediary server simplifies the overall process by centralizing data management and eliminates the need for direct USB connections or email attachments, thereby improving ease of operation while maintaining printing quality through proper data handling.
Solution Approach 2:
The patent implements preliminary rendering of print data at the computing device before transmission to the server. The print data is pre-processed and converted into an appropriate format suitable for mobile printing. This preliminary action ensures that the printing quality is maintained from the source, and the mobile terminal only needs to receive and print the already-processed data, simplifying its role and the overall process.
2Ease of operation
If traditional pull printing is implemented with a server, then printing convenience is improved, but additional costs for server purchase and maintenance are incurred
Solution Approach 1:
The patent makes the mobile terminal multi-functional by enabling it to serve dual purposes: as a portable computing device for content consumption and as a printing device. The mobile terminal runs a printing application that can receive print data from the server and directly print it using a connected printer. This eliminates the need for a dedicated server infrastructure, as the mobile terminal itself becomes the printing initiation point, thereby reducing server costs while maintaining printing convenience.
Solution Approach 2:
The patent enables the mobile terminal to autonomously handle the printing process by implementing a printing application that can independently communicate with printers, manage print jobs, and control the printing workflow. The mobile terminal acts as its own printing server, eliminating the need for external server infrastructure. This self-service capability allows users to print directly from their mobile devices without incurring additional server purchase or maintenance costs.
