End Subscript/Superscript Mode (ESC T)
1B 54
This controls stops subscript and superscript printing.
Set Print Direction (ESC U)
1B 55 NN
This control specifies bidirectional or unidirectional printing.
v
If NN is 1, unidirectional printing is selected.
v
If NN is 0, bidirectional printing (default) is selected.
Double-Wide Continuous Mode (ESC W)
1B 57 NN
This control turns double-wide printing on or off. When double-wide printing is on,
the width of subsequent graphic characters is doubled (the characters per inch
value is half of the single character value). For tabs, the font width is not doubled
(tab distance is based upon single character width).
NN is a one-byte hexadecimal value that turns double-wide printing on or off.
v
If NN is 1, double-wide printing is turned on.
v
If NN is 0, double-wide printing is turned off.
Note: Double-Wide Continuous Mode does the same function as Shift Out, except
double wide printing is not canceled when a new line begins.
Set Horizontal Margins (ESC X)
1B 58 LL RR
This control sets the left and right margins. The margins are specified in character
positions relative to the left edge of the physical page.
LL is a one-byte hexadecimal value from X'00' to X'FF', which specifies the starting
print position relative to the left edge of the physical page. If LL equals 0, the left
margin is unchanged.
RR is a one-byte hexadecimal number from X'00' to X'FF' that specifies the
rightmost print position relative to the left edge of the physical page. If RR equals 0,
the right margin is unchanged.
Notes:
1. Set Horizontal Margins should be followed by a carriage return (CR) control to
set the print position to the new left margin.
2. LL should be at least one character width less than the page width.
3. If RR is greater than the page width or is less than LL, RR is set to the page
width (MPP).
