9–27Epson FX Emulation
Backspace
ASCII Code BS
HEX Code 08
Purpose Moves the simulated print head to the left one character space toward
the first character column.
Comment Assures that the previous printable characters will be printed, then
moves the simulated print head one character space to the left at the
current pitch setting (which includes double wide and ESC SP).
If the simulated print head bumps into the left margin, it stops. This
command is ignored if a justification mode of ESC a n is set with
n 0, emulating the FX. If this code is sent immediately after
graphics printing, it moves the simulated print head back to the
beginning of the graphics.
Example Print and backspace two character positions.
