Image Forming Apparatus External Preview Interface

The patent introduces an external device (smartphone, tablet, or computer) as an intermediary to display the label image. The barcode printer generates the label image data and transmits it to the external device, which then renders and displays the image. This mediator approach allows detailed visualization without requiring a large display built into the printer itself, thus resolving the contradiction between detailed check capability and device complexity.

The display function is extracted from the barcode printer and relocated to an external device. Instead of incorporating a large display screen and touch panel into the printer, the patent separates the image generation function (remaining in the printer) from the image display function (moved to external device). This extraction eliminates the need for complex display components in the printer while still enabling detailed pre-printing checks.

The patent uses an external device as a mediator that already possesses display capabilities. Instead of manufacturing a printer with an integrated large display (which would increase manufacturing cost), the system leverages the existing display hardware of external devices like smartphones or tablets. This approach achieves detailed image viewing without incurring the high costs associated with integrating large displays into the printer.

The patent creates a digital copy of the label image data and transmits it to an external device for display. Rather than physically incorporating display components into the printer, the system copies the image data to an external platform that can render it. This copying approach avoids the manufacturing costs of integrated display hardware while maintaining the ability to perform detailed visual checks.

The patent leverages the external device's existing user interface capabilities (touch panel, display, processing power) as a mediator. The barcode printer maintains its core printing functions with minimal interface complexity, while the external device provides the enhanced user interface for image viewing and interaction. This distribution of interface functions resolves the contradiction by achieving high ease of operation without increasing printer complexity.

The patent utilizes the universal capabilities of external devices (smartphones, tablets, computers) that users already possess. These external devices serve multiple purposes: displaying the label image, providing touch interaction, and potentially storing or sharing the design. By leveraging this universal multi-functional hardware, the system achieves enhanced user interface capability without adding specialized complex components to the printer itself.
