Epson LQ-2180 User Manual page 129

High speed draft
When you choose On, the printer prints up to 480 cps (characters
per second) at 10 cpi (characters per inch). When you choose Off,
the printer prints up to 360 cps at 10 cpi.
Input buffer
When you turn on this setting, the printer's input buffer stores
up to 64KB of data sent from your computer, freeing up your
computer for other tasks while the printer prints. When you select
Off, the buffer cannot store data, so the computer must wait for
the printer to print each character before it sends the next
character.
Buzzer (beeper)
When you turn on this setting, the printer beeps when an error
occurs. See page 7-2 for more information on printer errors. If you
do not want the printer to beep when an error occurs, select Off.
Auto CR (carriage return)
This setting is available only in IBM 2391 Plus emulation mode.
When you select On, each line feed (LF) code or ESC J code
received by the printer is accompanied by a carriage return code.
This moves the print position to the beginning of the next line. If
the printer adds an extra line after every carriage return, select
Off.
A.G.M. (Alternate Graphic Mode)
When A.G.M. is on, the printer can use some advanced graphics
commands like those available in ESC/P2 mode. When you select
IBM 2391 mode, this setting is available. The default setting is off.
Font
You can select 6 fonts in default-setting mode. The following fonts
are indicated on the control panel and can't be selected by default
settings: Draft, Roman, Sans Serif, Courier, Prestige, and Script.
