Modular Printer Fiscal Cartridge Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiscal printers for commercial automation face issues with reliability, adaptability to different legal requirements, and maintenance, leading to potential fraud and operational disruptions, as well as unnecessary complexity and cost due to duplicated components and restrictive sealing requirements.
Innovation Solution
A modular printer design comprising a separate fiscal cartridge and printing module, allowing for adaptable fiscal control and maintenance without interrupting operations, with the fiscal cartridge containing all fiscal components and being removable independently, and a non-fiscal cartridge for situations without fiscal requirements, ensuring compatibility and reducing component duplication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printer uses a unified sealed structure to prevent fraud, then security against fraud is improved, but maintenance complexity increases and operational downtime increases
Solution Approach 1:
The printer is divided into separate functional modules: a fiscal control module containing the sealed fiscal memory and control board, and a printing module. The fiscal control module can be independently removed and replaced without affecting the printing module, allowing maintenance without breaking the fiscal seal and thus avoiding operational downtime while maintaining security.
Solution Approach 2:
The fiscal control module is extracted as a separate removable unit from the printing module. This extraction allows the fiscal components to be maintained or replaced independently through simple cartridge replacement, eliminating the need to break seals or interrupt fiscal operations during maintenance.
2Adaptability or versatility
If the printer is adapted to different fiscal legislations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The fiscal control module is designed as a universal interface that can accommodate different fiscal memory types and configurations through software configuration rather than hardware changes. The module can be adapted to meet various fiscal legislation requirements (Brazilian Convention 156/94, Romanian Urgency Ordinance No. 28/1999, etc.) without requiring different hardware architectures, thus maintaining simplicity while achieving versatility.
3Productivity
If thermal printing is used, then printing speed and efficiency are improved, but compliance with fiscal conventions decreases
Solution Approach 1:
The fiscal control module performs preliminary actions by storing fiscal data in secure non-volatile memory before printing occurs. The system validates and seals the fiscal data in advance, then uses thermal printing for efficient receipt generation. This preliminary sealing action ensures compliance with fiscal conventions requiring concomitant printing while allowing the use of faster thermal printing methods.

AI summary
PRINTER (1) WITH MODULAR CARTRIDGE made up of a printing module (2) and a modular (3) cartridge, in independent cabinets but in the same printer, being that said modular cartridge can be fiscal or a non-fiscal cartridge. Said printing module (3) comprises at least a printing mechanism (4), a paper support (5), an auxiliary connection board (7), and the latter's connection to the control board (8). In fiscal cartridges, a fiscal control board is provided, comprising the devices responsible for all fiscal control functions and also for the printing control. In case of printers that do not need fiscal control, the control board can be simplified to a board with printing control function only, making up the so-called non-fiscal cartridges.
