Margins, Left and Right
ASCII Code ESC [p1;p2 s
Hex Code 1B 5B p1 3B p2 73
Dec Code 27 91 p1 59 p2 115
Expression CHR$(27);“[p1;p2s”;
Purpose The p parameters are distances from the left edge of the
printable area of the paper in decipoints. They are internally
converted to column positions based on the current CPI setting.
The first print area will be one column to the right of the left
margin.
NOTE: The margins set with this sequence begin at the first physical print
position, not at the edge of the paper.
Discussion When operating at 10 CPI, the escape sequence ESC
[720;8784s will produce a one-inch (10 column) left margin with
column 11 as the first printable position. The print line length is
8784 decipoints minus 720, or 8064 decipoints (11.2 inches, 112
columns). If the normal print area of 13.2 inches is available, the
right margin is one inch. The last column represented by p2 is
the last print position and the right margin begins in the next
column.
Left and right margin default values are column zero and the
highest column number in use depending on the CPI setting,
shown below. This escape sequence is valid in graphics but
does not apply to bar codes. Default margins may be set by
using ESC [s.
Left Margin = column 0 minus Right Margin
10 CPI = column 136
12 CPI = column 163
13.3 CPI = column 181
15 CPI = column 204
16.7 CPI = column 226
When printing in proportional mode or line mixing, the margins
are converted to absolute positions for that line. If the printer
receives this command anywhere in a printable line, the
command will affect that line and subsequent printable lines.
