2.Xon/Xoff control
The data transmission from a host computer is controlled through the exchange of Xon(1116) command and Xoff(1316) command between the printer and the host computer.
When the data stored in the input buffer of the printer exceeds 4,046 bytes, the printer sends the Xoff command to the host computer.
Upon the reception of the Xoff command, the host computer stops to send the data.
If the data stored in the input buffer of the printer falls below 3,995 bytes, the printer sends the Xon command to the host computer.
Upon the reception of the Xon command, the host computer resumes sending the rest of the data.
∗When the printer fails (for example,
And then, after the printer gets back to normal, the printer sends the Xon command to the host computer.
