4.2.14 TEXT JUSTIFICATION CONTROLS

Comment:
It is often convenient to print one or more centered lines, or texts with right and/or
justified margins. This command causes text justification to be automatically perfor-
med while printing. The type of justification set depends on the value assigned to n:
n = 0 left (default)
n = 1 centered
n = 2 right
Justification is performed when the printer receives a CR, LF or FF code, or when the
input buffer is full. The ESC a n command should always be given at the beginning of
a new line, as all data preceding it on the same line is lost. If bit image graphics ele-
ments and text elements are mixed in the line, justification is not performed properly.
