ON LINE SW: When the POWER switch is turned ON after paper has been
loaded, the printer enters the ON LINE mode and can be utilized
in conjunction with a host computer.
Depressing the ON-LINE switch will set the printer in the
OFF-LINE mode and cause the green LED to go out. The switch
does not function while the printer is actively engaged in printing.
The printer is automatically placed OFF-LINE if the paper
supply is exhausted or if a mechanical error occurs in the printer.
The operations of the Line Feed and Form Feed Switches are
effective only while the printer is OFF-LINE.
