One Char Enquiry
When enabled, 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.
Poll Character
This option is used when One Char Enquiry is enabled. 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.
