Backspace
107
Backspace
ASCII Code BS
Hex Code 08
Dec Code 08
Purpose Moves the logical print head to the left one character space
toward the first character column.
Discussion Assures that the previous printable characters will be 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
Image Graphics command (ESC K, ESC L, ESC Y, or ESC Z),
your printer will backspace into the graphic pattern, the number
of dots depending on the current cpi setting. For an Epson FX-
1050 printer, one Backspace will send 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:
Bell
ASCII Code BEL
Hex Code 07
Dec Code 07
Purpose Sounds the printer's buzzer/beeper.
Discussion The BEL function will sound the buzzer/beeper for 0.2 seconds
upon receipt of this command.
Cancel Line
ASCII Code CAN
Hex Code 18
Dec Code 24
Purpose Clears all unprinted data from a line, but does not affect control
codes.
Discussion You can use this control code to delete a line, but do so with
caution to avoid possible misprinting. This control code cancels
