Form In

Used for parallel printers only. This command is NOT supported in a standard IEEE 1284 interface, however, and should not be used. This command may be used with a non-standard parallel interface with no bi-directionality, but it is recommended that you use other status commands (Status: 3 Bit and Status: 6 Bit) to detect form presence instead.

Causes pin 13 on the 25-pin communication cable connector to indicate the status of the Form-In sensor. 1 = form not present. Internal switch pack #3, switch 8 must be set to ON.
