Purpose Moves the logical print head to the left one character space
toward the first character column.
Comment Assures that the previous printable characters are printed, then
moves the logical print head one character space to the left at
the current pitch setting (which includes double wide and ESC
SP). If the logical print head bumps into the left margin, it stops.
†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.
†If one or more Backspace control codes follow directly after a Bit
ImageGraphics 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.
Example If you were to print five “T” characters, then two BS commands,
then two “=” characters, the output would look like the sample
below.
