POWER INDICATOR - Glows red when the power in on or blinks when the printer is out of paper or some other error occurs.
BOLD KEY and INDICATOR - Pressing this key selects boldface printing. DRAFT INDICATORS (80, 96, 136) - Glows green to indicate the number of characters per line when the priner is in the draft mode (set by the Mode key or the software control).
NLQ INDICATOR - Glows green when the printer is printing in the Near Letter Quality (NLQ) mode (set by the Mode key or the software control). MODE KEY - Changes the print mode every time it is pressed.
TOF KEY - Ejects the current sheet, feeds a new sheet, and moves the print head to the left margin.
PAPER FEED KEY - Advances the paper one line at a time when the On Line indicator is off. If you hold the key down, you’ll get consecutive line feeds, one after the other.
ON LINE KEY and INDICATOR - Glows green when the printer is ready to receive data from your computer (on line). When the printer is off line, it sends a signal to the computer indicating that it cannot accept data. Pressing the On Line key switches the printer on line and off line.
