Quiet/Quality Switch
When the printer is in Ready mode, pressing the Quiet/Quality switch puts it
into Quiet mode.
When the printer is off-line, (the Ready indicator (RDY) is blinking), the
Quiet/Quality switch allows you three choices of print quality:
1 Letter Quality (LQ), which prints at 83 characters per second (CPS).
2 Draft Quality (DQ), which prints at 250 CPS.
In both cases, an indicator lights up next to the print quality you have
selected.
3 If no indicator lights up, the print quality is controlled through software
commands.
The LA75 Plus has one other print quality, Near Letter Quality (NLQ), which
prints at 125 CPS. This mode is only selectable through sofware commands.
Note: All CPS speeds listed in this guide are quoted at their maximum burst
speeds (Normal Mode). For more information on CPS, see Section 7.5 in
Chapter 7.
Protocol Indicator and Switch
The Protocol switch lets you change the way the printer communicates with
your computer system. This switch is only operative when the printer is in
a paused state, and a print job has finished. (There is no data left in the
print buffer.) Press this switch to toggle between DEC protocol and IBM X24E
protocol.
When DEC LED is On, DEC mode is selected; when DEC LED is Off, IBM
mode is selected. The protocol can also be changed by the application software.
Line Feed (LF) Switch
The LF switch advances the paper in the printer one line at a time. Continued
pressure on the switch advances the paper a number of lines.
Form Feed (FF) Switch
The FF switch advances the paper in the printer to the top of the next form.
