Star Micronics LC24-15 user manual Clearing the buffer

Clearing the buffer

When DIP switch 2-l is ON, the printer stores received data in a large memory buffer. This creates a problem when you want to abandon a printing job and restart: the printer may be holding much more data in its buffer than it has actually printed, and this unprinted data must be cleared out before restarting. Turning power off is one way to clear the buffer, but there is another way:

1.Halt the printing program on the computer. If printing stops immedi- ately, the buffer is clear and the rest of this procedure is unnecessary. If printing does not stop, continue as follows:

2.Press the ( ON LINE ) button to set the printer off-line. Printing will now stop, but there may be data remaining in the buffer.

3.Press and hold the ( ON LINE ) button.

4.Press and hold the (SZKiZ)button. Continue holding these two buttons down. In about three seconds you will hear a beep tone signaling that the buffer has been cleared.

5.Release these buttons, make any necessary control panel settings, then set the printer back on-line.

It is essential to halt the printing program on the computer before you go off- line. Otherwise, when you go back on-lint the computer will start sending data again and the printer will continue printing, with missing data where the buffer was cleared.
