The print format can be right, center, or left justified. The value of <n> specifies
the justification.
The power on default is left justified.
Notes
1. Lines that have mixed size characters within them cannot be centered. For
example, a line with mixed single- and double-high text cannot be centered.
If a line of print is to be double-high and centered, the change to single-high
print must be done after the line terminator for the double-high line.
For example, [ESC] W <3> Centered [ESC] W <0> [CR] will not print
correctly because the printer assumes that more data will follow the [ESC]
W <0>. The correct line would be: [ESC] W <3> Centered [CR] [ESC] W
<0>.
2. Justify commands do not effect graphics.
