This section summarizes requirements for scanners and digital cameras that use a parallel port.
10. Parallel hardware complies with PC 97 parallel requirements
| Required |
All parallel hardware must comply with the Plug and Play requirements for parallel ports, as defined in the "Serial, Parallel, and Wireless Support" chapter in this guide. This includes implementing the required support in the Plug and Play Parallel Port Devices Specification v. 1.0b.
These requirements and recommendations ensure that a parallel device has complete Plug and Play capabilities. For example, a user must be able to attach any parallel peripheral to any parallel connector; the operating system should recognize it automatically, load and initialize the appropriate drivers, and then make the device available for use.
Each parallel scanner or digital camera must have a Plug and Play device identifier for an IEEE 1284 peripheral. At a minimum, the device-ID string
must contain these keys: MANUFACTURER, MODEL, CLASS, and DESCRIPTION.
A parallel device can also be designed to meet the recommendation to support
the COMPATIBLE key in the device identification string, as defined in the "Serial, Parallel, and Wireless Support" chapter.
