| Catalog identity | StarTech.com ICUSB1284D25 6 ft USB 2.0 Type-A male to DB25 female parallel adapter cable |
| Verified protocol / model information | StarTech identifies a 6 ft (about 1.8 m) USB-to-DB25 parallel adapter cable. USB host signaling is converted to a parallel-printer interface by active electronics; the DB25 output is not a serial RS-232 port. |
| Connector ends | USB TYPE-A HOST → DB25 PARALLEL; diagram is schematic, not a pinout map. |
Physical & electrical compatibility
Requires a compatible USB host/driver and printer that accepts the adapter’s parallel interface. A DB25 connector is used for different electrical interfaces; never assume this parallel output is RS-232 or IEEE-1284 host capability identical to a native port. Check supported printer functions; legacy dongles, scanners, and bidirectional devices may not work.
Archival & handling notes
Keep model, driver, and known-supported printer with the adapter. Inspect USB plug and DB25 contacts, and do not force a parallel plug into a serial device. Record whether the printer supported bidirectional/status functions.
Record provenance, condition, label photographs, exact full part number/revision, host system, and any test method/result. Preserve packaging and source documents with the cable when available.
