Printer Paper Registration Screen Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers delay printing and force users to unnecessarily input paper attributes because they only start printing after the paper registration screen is ended, even if printing conditions are met during its display.
Innovation Solution
A printer with a display unit, printing unit, and control unit that allows printing to start when prescribed conditions are met during paper registration screen display, using attributes registered before the screen was displayed, without requiring the screen to be closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printer requires the paper registration screen to be ended before printing can start, then paper attribute registration is ensured, but printing is unnecessarily delayed and productivity decreases
Solution Approach 1:
The printer performs preliminary paper attribute registration before the paper registration screen is displayed. When a paper feeding unit is inserted or removed, the printer automatically registers paper attributes in advance (step S102), so that when printing conditions are met during screen display, the attributes are already available and printing can start immediately without waiting for screen closure.
2Stability of the object's composition
If the printer waits for the paper registration screen to be ended before starting printing, then screen display completeness is maintained, but printing delay occurs and time is lost
Solution Approach 1:
The system performs preliminary actions during screen display by checking printing conditions (step S103) and preparing to start printing immediately when conditions are met, rather than waiting for screen closure. This allows the printer to maintain screen display completeness while avoiding unnecessary printing delays.
Solution Approach 2:
The printer dynamically adjusts its operation based on the state of the paper registration screen. When printing conditions are satisfied during screen display, the printer can start printing immediately (step S105), making the system flexible rather than rigidly waiting for screen closure, thus reducing time loss.
3Measurement precision
If the printer forces users to input paper attributes even when printing conditions are met, then attribute accuracy is ensured, but ease of operation decreases
Solution Approach 1:
The printer performs preliminary paper attribute registration (step S102) so that when printing conditions are met during paper registration screen display, the attributes are already registered and printing can start immediately without forcing users to input attributes again, thus improving ease of operation while maintaining attribute accuracy through the preliminary registration process.

AI summary
A printer includes a display unit, a printing unit and a printing control unit. The display unit is configured and arranged to display a paper registration screen for registering or confirming attributes of paper held in a paper feeding unit when display conditions have been satisfied. The printing unit is configured and arranged to execute printing. The printing control unit is configured to, when prescribed printing start conditions are satisfied during a period in which the paper registration screen is being displayed, control the printing unit to start printing job using the attributes registered before display of the paper registration screen as the attributes of the paper held in the paper feeding unit used with the printing job.
