Printing Apparatus Standard Print Function Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cloud print services cannot determine whether a printing apparatus supports a standard print function, leading to impaired convenience for information processing apparatuses.
Innovation Solution
A printing apparatus is equipped with a remote printing unit, local printing unit, and a transmission unit to inform a print server that it supports a standard print function, enabling accurate determination and improved convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the printing apparatus transmits support information indicating standard print function to the print server, then the information processing apparatus can determine compatibility and improve convenience, but the communication protocol and data transmission complexity increase
Solution Approach 1:
The patent makes the printing apparatus compatible with both standard print functions (AirPrint, Mopria) and cloud print services by implementing multiple communication interfaces. The apparatus can transmit support information for standard print functions to the print server, enabling information processing apparatuses to determine compatibility. This multi-functionality approach allows the same printing apparatus to serve both local standard printing and remote cloud printing needs without requiring separate devices.
Solution Approach 2:
The print server acts as an intermediary between the printing apparatus and information processing apparatuses. The printing apparatus transmits support information to the print server, which then makes this information available to information processing apparatuses. This mediator approach simplifies the communication protocol by centralizing the information exchange through the print server, reducing direct communication complexity between the printing apparatus and multiple client devices.
2Adaptability or versatility
If the printing apparatus supports both remote printing via print server and local printing directly, then versatility is improved, but device complexity increases
Solution Approach 1:
The printing apparatus is designed with dual printing capabilities: remote printing through a print server and local printing directly from information processing apparatuses on the same network. This multi-functionality allows the apparatus to adapt to different usage scenarios and user preferences, providing versatility without requiring separate printing devices for different modes.
Solution Approach 2:
The printing apparatus dynamically switches between remote and local printing modes based on the source of print jobs. The apparatus can receive print jobs from the print server (remote mode) or directly from information processing apparatuses (local mode), adjusting its operational state accordingly. This dynamic capability enables flexible adaptation to different printing scenarios while maintaining a unified device architecture.

AI summary
A printing apparatus includes a remote printing unit for executing printing in accordance with a print job transmitted from a print server, a local printing unit configured to execute printing in accordance with a print job transmitted from an information processing apparatus connected to a same network as the printing apparatus, and a transmission unit configured to transmit, to the print server, support information indicating that the printing apparatus supports a standard print function included as standard in an operating system of the information processing apparatus.
