n (Hex) Print Position
0,30 No printing
1,31 Above the bar code
2,32 Below the bar code
3,33 Both above and below the bar code
(53) Specifying/Clearing Black/White reverse printing (GS B n)
Code: [1D] h + [42] h + n
* (0 ≤ n ≤ FF) Data are expressed in Hex code.
This command specifies or clears printing of black/white reversed characters.
• In n, the least significant bit (n0) becomes enabled.
The least significant bit (n0) is as follows.
n0 = 0: Clears printing of black/white reversed characters.
n0 = 1: Specifies printing of black/white reversed characters.
• Internal characters and downloaded characters can be printed as black/white re-
versed characters.
• The space to the right of characters, set by ESC SP, is also the object of black/
white reversed printing.
• Bit images, downloaded bit images, bar codes, HRI characters and portions skipped
due to HT, ESC $, ESC ( are not influenced.
• Spaces between lines are not influenced.
• Specification of black/white reversed printing has priority over underline specifi-
cations. Therefore, underlines are not added to black/white reversed characters,
even when underline is specified. However, the underline setting state does not
change.
• The initial value is “n0 = 0”.
(54) Selecting the HRI character print position (GS H n)
Code: [1D] h + [48] h + n
* (0 ≤ n ≤ 3, 30 ≤ n ≤ 33) Data are expressed in Hex code.
This command selects the HRI character print position when a bar code is printed.
• n has the meanings in the following table.
• HRI characters are printed in the font selected by GS f.
• The initial value is “n = 0”.
