Command Summary
for
LQ/FX Emulation
ESC w
This command produces double-height characters, but differs
operationally in the following ways:
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 will only print the bottom half of each character. The
EPI-4000 prints the entire character when you are printing on
single sheets. If you are printing on continuous paper, the
EPI-4000 does
not
print.
FX
mode-When you combine this command with ESC W to
produce double-width, double-height characters, FX series
printers do not increase the stroke weight for vertical lines. In FX
emulation mode,
the
EPI-4000 does increase
the
vertical line
weight.
ESC S0, ESC Sl, ESC w, ESC -
When you print on continuous paper, the characters described
below cannot be printed:
l
Superscript characters and double-height characters on the first
line of the logical page
l
Subscript characters and underlined characters on the last line of
the logical page.
ESC C, ESC C0
When you send the ESC C or ESC C 0 command to change the page
length on LQ or FX printers, you can print more than one page on
the same sheet of continuous paper. Because the EPI-4000 processes
data page-by-page, each page must be printed on a separate sheet of
paper, so exact LQ or FX emulation cannot be provided. Problems
will occur when the page length set with the ESC C or ESC C0
command differs from the actual page length.
