POWER LAMP - Glows green when the power is on.
READY LAMP - Glows green when the printer is ready to ac- cept data. This light flickers
during transmission. Don’t worry about the flicker; it’s normal!
ON LINE LAMP - Glows green
when the communication lines to your computer are open.
LF BUTTON - Stands for “Line Feed,” and allows you to ad- vance the paper one line at a time when the on line lamp is off. If you hold the button down, you’ll get consecutive line feeds, one after another.
FF BUTTON - Stands for “Form Feed.” When you tap this button while the on line lamp is off, you advance the paper to the top of a new page or “form.”
ON LINE BUTTON - | Lets you change the printer | status between |
| - | ||
“off line,” and “on line”. When it’s on line, the printer can receive |

data from the computer. When it’s off line, the printer sends a |
|
| ||||
signal to the computer | indicating | that it cannot accept | data. | - | - | |
