Epson Emulation Exceptions and Differences
Because of mechanical differences between your printer and Epson p rinters
(moving printhead serial matrix printers), some Epson features are
approximated or not supported.
Epson codes that produce different behavior in your printer are indi cated
by a “dagger” () in the Control Code Index and code section.
Epson bit-image graphics are supported, including all plotter and CRT
densities.
Manyc haracter sets are available, including IBM-PC Graphics (IBM Code
Page 0437) and Epson. You can configure the zero character to contain a
slashornoslash.
Like the Epson FX-1050, the Double Wide print control codes (ESC W,
SO) double the character width. Unlike the Epson FX-1050, however,
these codes do
not
double the inter-character spacing. The formulas for
total character spacing are as follows:
Epson FX-1050 2 (char +1dot+space)
Epson Emulation 2 (char +1dot)+space
TheCo ndensed Print (SI) control code condenses the character width but
not
the inter-character spacing, unlike the Epson FX-1050, which
condenses both character width and spacing.
If one or more Backspace control codes follow directly after a Bit Image
Graphics command (ESC K, ESC L, ESC Y, or ESC Z), the printer
backspaces into the graphic pattern, the number of dots depending on the
current cpi setting. For an Epson FX-1050 printer, one Backspace sends
the logical printhead directly to the beginning of the graphics pattern.
When backspacing over proportionally spaced characters, Epson printers
move back the width of each proportional character; this emulation moves
back based on the current cpi setting, as if proportional spacing is
disabled.
