Part 14: Structural Design Classification (Standalone, Modular, Embedded, and System-Integrated Architectures) |
1. Introduction to Structural Design in Barcode Printers |
1.1 Structural design classification refers to how a barcode printer is physically and functionally constructed as a system. Unlike printing technology (which defines *how images are produced*) or application environment (which defines *where printers operate*), structural design defines *how the printer is built and integrated into larger workflows*. |
1.2 This classification is essential because it determines: |
* System independence |
* Automation capability |
* Expandability |
* Integration with enterprise infrastructure |
* Maintenance strategy |
1.3 In modern barcode ecosystems, structural design is closely linked with digital transformation, automation, and Industry 4.0 systems. |

|

2.1 Barcode printers are generally classified into four major structural categories: |
1. Standalone printers |
2. Modular printers |
3. Embedded printers |
