Setting the text alignment
Function:
ESC a (n) sets the following text alignments depending on n (0 ... 3):
– flush left : n = 0 (default value)
– centered : n = 1
– flushright:n=2
– margin justification : n = 3
The adjustment takes place after the output of the following control commands:
– CR (Carriage return, is output implicitly, for example, by the print command
PRINTLF)
– LF (Line feed, is output implicitly, for example, by the print command PRINT
LF)
– VT (Vertical tabulation)
– FF (Form feed)
– After an additional command (ESC [ ...)
With margin justification the text is aligned flush left and flush right. Thereby the
word spacing and the character spacing are increased, if necessary. The divisi-
on of a text into print lines takes place automatically. Therefore LF or CR com-
mands, for example, via the print command PRINTLF, should only be used
within a margin justification text in order to set a paragraph in the text.
