Most Significant Bit Commands (Epson); Paper-Out Sensor Commands (Ibm/E/Ml) - Oki MICROLINE ML521 Reference Manual

Most Significant Bit Commands (Epson)

ML320 E/I, ML321 E/I
Function
Set Most Significant Bit (MSB) to Zero
Set MSB to 1
Cancel MSB Control
The ESC = command sets the most significant bit (MSB) of an 8-bit data input to zero. The ESC
> command sets the MSB to one. The ESC # command cancels the MSB control established by
either command and all data is interpreted exactly as sent from the computer.

Paper-Out Sensor Commands (IBM/E/ML)

ML320 E/I, ML321 E/I
ML320 Std., ML321 Std.
Function
Paper-Out Sensor On
Paper-Out Sensor Off
The paper-out sensor detects when less than one inch of paper remains (0.5-inch for
ML390/391T printers). When this happens, the alarm light goes on and the printer is
deselected. This command overrides the sensor so that you can print closer to the bottom of the
page. (The feature is also menu selectable.) Be careful if you use this feature, since it lets the
printer continue printing when there's no more paper. This can cause loss of data and may
damage the printhead.
