9. Bar code and enlarged character
(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”.
