It should be noted that inquire commands are preprocessed (looked at and processed as they are received).
This prevents the buffer from being filled with inquire commands. However, if data pass-through is active
inquire processing must be off. If it is on, the inquire sequences will be stripped from the pass-through data.

Parallel Port Plug and Play

Microsoft Windows implements Plug and Play (PnP) by doing a special parallel, IEEE 1284 inquire during
boot. The Series 90PLUS 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, 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 of the interface
signals.
The PnP response follows.
