4-12 Epson TM-U950 Commands
ESC SP n
Set right-side character spacing
Hexadecimal code: 1B 20 n
Range:
n = 0-255
Sets the character spacing for the right side of the character using the horizontal motion units.
Notes:
- The right-side character spacing is [n x (horizontal motion units)] inches.
- This command is effective when the right side character spacing
[n x (horizontal motion units)] = 32/150 inches or less.
- The right-side character spacing for double-width mode is twice the normal value.
- If the value of n is out of the specified range, the printer ignores this command.
Default:
n = 0

Hexadecimal code: 1B 21 n
Range:

Selects print mode(s) using n as follows:
Bit Off/On Hex Decimal Function
0 Off 00 0 Character font 9 x 9 selected.
On 01 1 Character font 7 x 9 selected.
1, 2 - - - Undefined.
3 Off 00 0 Emphasized mode not selected.
On 08 8 Emphasized mode selected
4 Off 00 0 Double-height mode not selected
On 10 16 Double-height mode selected
5 Off 00 0 Double-width mode not selected
On 20 32 Double-width mode selected
6 - - - Undefined.
7 Off 00 0 Underline mode not selected
On 80 128 Underline mode selected
Notes:
- When both double-height and double-width modes are selected quadruple size characters
are printed.
- Bi-directional printing may cause printing position misalignment between the upper and
lower halves of the characters during double-height enlarged printing. Therefore, it is
better to select unidirectional printing (using ESC U) for double height enlarged printing.
- If you select the underline mode, some printed characters may be difficult to read because
the underline overlaps the lowest dots in the characters.
