Justification (JFY)
ASCII Code ESC [ Ps SP F
Hex Code 1B 5B Ps 20 46
Dec Code 27 91 Ps 32 70
Purpose Aligns text at left and right margins.
Discussion Justification changes the spacing between words. With a justified line,
the first character of the first word is flush with the left margin, or at the
line home position if it differs from the margin setting. The last character
of the line will be at the right margin. Once enabled, justification remains
on until you turn it off.
Justification places the printer in plot mode. Subsequent text is then printed
in the plot font selected. If you do not select a font, solid rectangles are
plotted.
The printer evenly spaces each word on a justified line. The space character
(SP) indicates a word space to the printer, and you set the limits for word
spacing with the Ps parameter, as follows:
Ps
0 Turn off justification (default)
Printer Action
Turn on justification with limits2
Turn on justification without limits?2
When justification with limits is set (Ps = 2), the printer does not shrink or
expand the space character beyond the limits set by the current font (usually
in the 50–200% range). If you select justification without limits (Ps = ?2),
the printer can shrink the space character to zero.
The printer will not make hyphenation or end–of–line determinations when
justification is turned on, nor will autowrap operate with justification turned
on. Use the following sequences or control characters to make End–of–line
determinations:
• Carriage Return <CR>
• Form Feed (FF)
• Line Feed (LF)
