ENQ/STX protocol

In addition to this XON/XOFF message, the possibility exists of re-

 

 

 

 

questing a status byte from the printer using the ENQ code (hex. 05,

 

 

dec. 5).

The STX code (hex 02, dec. 2) is used to clear any error messages (parity error, buffer overflow).

Status byte

Bit 0 – 1

BUSY

 

Bit 1 – 1

Off Line

 

Bit 2 – 0

Paper end

 

Bit 3 – 1

Always 1

 

Bit 4 – 1

Cover open

 

Bit 5 – 1

Buffer overflow

 

Bit 6 – 1

Parity or frame error

 

Bit 7 – 0

Always 0

STX (hex02)

Clears any previous parity or framing error as well as

 

any buffer overflow error.

ENQ (hex05)

The current printer status is sent to the host.

XON/XOFF

This protocol is automatically used for data flow control

 

and printer status handling.

HandThr.=ON

The STX and ENQ characters are not filtered out of the

 

data stream and control the interface in addition.

HandThr.=OFF The STX and ENQ are filtered out of the data stream and handled immediately by the interface.
