[Notes] • Set n = 26 to complete recover the paper.
• WARNING: setting n = 26 is not recommended for paper roll with low weight.
[Default] n = 15 mm

Hex 1D 21 n
Decimal 29 33 n
[Range] 0 ≤ n ≤ 7, 16 ≤ n ≤ 23, 32 ≤ n ≤ 39,

[Description] Selects character height and width, as follows:
• Bits 0 to 3: to select character height (see table 2).
• Bits 4 to 7: to select character width (see table 1).
Table 1 Select character width Table 2 Select character height
HEX Decimal Width HEX Decimal Height
00 0 1 (normal) 00 0 1 (normal)
10 16 2 (width = 2x) 01 1 2 (height = 2x)
20 32 3 (width = 3x) 02 2 3 (height = 3x)
30 48 4 (width = 4x) 03 3 4 (height = 4x)
40 64 5 (width = 5x) 04 4 5 (height = 5x)
50 80 6 (width = 6x) 05 5 6 (height = 6x)
60 96 7 (width = 7x) 06 6 7 (height = 7x)
70 112 8 (width = 8x) 07 7 8 (height = 8x)
[Notes] • This command is effective for all characters (except HRI characters).
• If n falls outside the defi ned range, this command is ignored.
• Characters enlarged to different heights on the same line are aligned at the baseline or
topline.
• $1B $21 can also be used to select character size. However, the setting of the last
received command is the effective one.
[Default] n = 0
