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:

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 and 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 sequences
Start (alternate) .................... ESC w 1 1B 77 31 27 119 49 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 and 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 sequence
End ....................................... ESC ESC W 0 1B 1B 57 30 27 27 87 48 does not change the current character spacing.
Double-wide printing................ ESC W n 1B 57 n 27 87 n This sequence starts and ends double wide printing, where-
Start ...................................... ESC W 1 1B 57 31 27 87 49 in characters print twice their normal width. This sequence
End ....................................... ESC W 0 1B 57 30 27 87 48 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 accommodate
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 spacing. 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 combinations. The
value of variable n determines which modes are on and which
are off. To find the correct n value, add up the numbers 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 underscore,
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.
