Epson Action Laser II - Manual (Page 273)

LQ and FX Emulation Modes
ESC x
This command is normally used to select between draft and LQ
quality with an LQ or FX series printer. However, this command has
no effect on your printer’s print quality since all characters are
printed at 300 dpi (dots per inch) Letter Quality.
ESC w
This command produces double-height characters but differs
between LQ and FX modes, as follows:
LQ mode-If you send the ESC w command when the print position
is set at the first line of the logical page, LQ series printers print only
the bottom half of the characters. Your printer prints the entire
character.
FX mode-When combining ESC w and ESC W to produce double-
width, double-height characters, FX series printers do not increase
the stroke weight for vertical lines. Your printer in FX emulation
does increase the vertical line weight. Also, when this command is
sent with the print position set at the first line of the page, the FX
changes the baseline position in order to print the entire character.
For your printer, the baseline is not changed.
ESC &, ESC K, ESC L, ESC Y, ESC Z, ESC *, and ESC ^
This printer uses an image processing technique that emulates, as
closely as possible, the image densities available on FX and LQ
printers. Because of this process, the graphics commands listed
above do not produce exactly the same output on the printer that
they would on an Epson FX or LQ printer.
