One Char Enquiry
When enabled, and the IGP feature is available, a status byte is sent back to
the host when the poll character or the command SFCC enquiry is sent to the
printer (serial interface only). The poll character is received and the status
byte is sent whether the printer is online or offline. The SFCC enquiry will only
be processed when the printer is online.

This option is used when One Char Enquiry is enabled and the IGP feature is
available. Whenever the printer receives this character, it sends aresponse to
the host indicating the current state of the printer. It may be configured from 0
through 255. The default value is 0.
