Parallel Port Plug and Play
Microsoft Windows implements Plug and Play (PnP) by doing an IEEE 1284 inquire during boot.
The Series 150 Printer will respond to this inquire if IEEE 1284 is active.
If the Windows PnP configuration flag is set in the printer, IEEE 1284 will be active for all
parallel port modes. For example, Windows PnP in parallel mode forces IEEE 1284. For PnP to
work, the host must have an IEEE 1284-compatible port adapter, and the cable used to connect to
the printer must support all the interface signals. The PnP response follows.
