Double-high / double-wide ESC [ @ EOT 1B 5B 40 04 27 91 64 4 The value of variable n2 determines whether double-wide
printing (continued) NUL NUL NUL 00 00 00 n1 n2 0 0 0 n1 n2 printing starts or ends:
n1 n2
Variable n2
Double-Wide ASCII Hex Dec
No change NUL 00 0
End SOH 01 1
Start STX 02 2
For example, to start double-high and double-wide
printing with line spacing set to 3 lpi, the correct sequence
is 27 91 64 4 0 0 0 34 2 (decimal).
Double-high printing These sequences start/end double-high printing, where-
Start ................................ ESC ESC H 1 1B 1B 48 31 27 27 72 49 in characters print twice their normal height. The
Start (alternate)............... ESC w 1 1B 77 31 27 119 49 sequences do not change the current line spacing.
End ................................. ESC ESC H 0 1B 1B 48 30 27 27 72 48
End (alternate) ................ ESC w 0 1B 77 30 27 119 48
Double-wide printing ........ ESC ESC W n 1B 1B 57 n 27 27 87 n This sequence starts/ends double wide printing, where-
Start ................................ ESC ESC W 1 1B 1B 57 31 27 27 87 49 in characters print twice their normal width. This
End ................................. ESC ESC W 0 1B 1B 57 30 27 27 87 48 sequence does not change the current character spacing.
Double-wide printing ........ ESC W n 1B 57 n 27 87 n This sequence starts/ends double wide printing, where-
Start ................................ ESC W 1 1B 57 31 27 87 49 in characters print twice their normal width. This
End ................................. ESC W 0 1B 57 30 27 87 48 sequence also doubles the character spacing to
accommodate the wider characters. A DC4 code does not
turn off double-wide printing started with this sequence.
One-line double-wide ......... ESC SO 1B 0E 27 14 This sequence starts and ends double wide printing on the
printing current line and doubles the character spacing to
accommo-date the wider characters. A DC4 code or any
control code or escape sequence that causes paper
movement ends double-wide printing and resumes normal
character spac-ing. The ESC ESC W 0 and ESC W 0
sequences also end double-wide printing started with ESC
SO.
Set master print mode....... ESC ! n 1B 21 n 27 33 n This sequence sets many unique print feature combina-
tions. The value of variable n determines which modes
are on and which are off. To find the correct n value, add
up the num-bers of the desired features:
0 - 10 pitch 4 - Condensed 32 - Dble-wide
1 - 12 pitch 8 - Shadow 64 - Italic
2 - Proportional 16 - Bold 128 - Underscore
For example, to select 12-pitch, shadow, italic and under-
score, the correct n value is 201 (1 + 8 + 64 + 128 = 201).
This sequence ends all print features in the list that are not
selected. Also, a proportional printing selection overrides
10- and 12-pitch selections.
