| Layer | Name | Role | |-------|------|------| | | Software using the data | Photoshop, PaintShop Pro, PaperPort | | Data Source Manager | TWAIN manager (twain_32.dll on Windows) | Finds and loads the correct Data Source | | Data Source | The actual "TWAIN driver" | Talks to the hardware, provides UI for scanning settings |
If an application asks for a TWAIN source, you need the manufacturer’s scanner driver that includes TWAIN support — not a separate universal driver.
| | | Scanner Driver | |---|----------|--------------------| | Type | Communication protocol | Low-level hardware interface | | Example | TWAIN 2.5 specification | Epson Scan 2 driver (USB/serial) | | Provides | Standardized functions (acquire, set resolution, etc.) | Direct control of motors, lamps, CCD sensors |
