[Function] Selects red/black substitute function
Selects characters targeted for adornment with m = 1 (ANK) or m = 2 (Kanji characters), and selects the
<ESC> "4"/<ESC> "5" command functions with n.
Sets the handling of adornment to space characters (ASCII 20Hex) with m = 83 ("S").
This command is enabled only when in a state where adornment is cancelled by <ESC> "4" (when <ESC> "5"
was specified).
When m = 1, 48 ("1") Targeted characters = ANK
m n <ESC> "4"/<ESC> "5" Command Functions (ANK)
1 , 49 0 White/black inverted printing (1 Pass)
1 , 49 1 <Option 1> White/black inversin (5 x 9 font print) + enhancing (2 passes)

When using <ESC> "5" to cancel adornments, it returns to the previously set adornments. (Adornments such as under-
line, upper line, double-tall expanded and enhancing are cancelled if there is no command to set them (for example the
<ESC> "-" 1 specification for underlines).
Precautions for selecting <Option 1>
1. Prints white/black inverted characters using 5 x 9 fonts regardless of the current font size
setting.
2. Inserts a one dot string of black printing to the head of the white/black inverted charac-
ters.
3. Printing data created on a conventional red/black printer, using 1 and 2 above, there are
cases in which the printing position will shift to the right and a line of printable characters
reduced.
4. Download registered characters defined with 5 x9 fonts are printed regardless of the cur-
rent font setting (7x9/5x9).
5. Must not set "ANK default dot count = many" with the memory switch. (This will cause a
white line to appear between characters.)
Precautions for selecting <Option 2> and <Option 3>
1. Do not apply an upper line or an underline when rotating 90 or 270 degrees.
