(1) Executing backspacing: BS
Format: ASCII BS
Hex 08
Decimal 08
Function: Executes backspacing.
When the BS command is executed, the printing position moves to the
previous character position on the left. The BS command is valid up to
the left margin. A BS command issued on the left margin is ignored.
When a BS command is issued when there is a character on the left with
proportional printing selected, the printer backspaces to that character. If
there is no character or another BS command has just been executed, the
printer backspaces by one space.
(2) Executing line feeding: LF
Format: ASCII LF
Hex 0A
Decimal 10
Function: Executes line feeding.
After printing data, the printer feeds one line by the enlarged character
line feed pitch, which differs depending on whether VMI is valid (by the
DC4 DC4 j command) or not.
VMI valid: Preset VMI amount
VMI not valid: (24 + cell offset)/180” x cell expansion
Line feeding involves a carriage return if the LF SETTING option is set to
LF + CR in the EXTENDED SETUP MODE.
If the bottom margin is specified and the cell size (i.e., 24/180” x cell
expansion) is greater than the printable area in the CSF, cut sheet, or
fanfold paper mode, form feeding is executed and then printing is
executed. If the printing position is at the TOF position, printing is
executed up to the bottom margin without executing form feeding, and
excess data is not printed.
The default pitch is “1/6” x cell expansion”.
