Print Rotation Commands

Rotated print capabilities are available. The print mode commands listed below rotate
the print in any of three 90° orientations. In 90° and 270° rotated mode, the print data is
first buffered by the printer, processed (rotated), and then printed in one of three fonts.
Consequently, printing time is delayed. In 180° mode, the print is simply inverted and
mirrored, and no delay occurs.
In rotated 90° and 270° mode, the printer can support up to 40 lines of rotated print with
up to 128 characters per line. One single pass and two double pass fonts with
emphasize and enhanced attributes are available.
In free format rotated 90° and 270° mode, the print length is determined by the length of
the longest line entered. In line formatted mode, the line length is set not by the longest
line entered but by the maximum line length specified by the set line length command.
A line spacing table controls the spacing between lines. The table is defined by the
rotated print line spacing ([ESC] u ...) command or by inserting [LF] or [ESC] J <n>
commands in the rotated data. The [ESC] u command specifies the number of dots to be
added between each printed line. Each line has an entry in the table. There is space for
40 lines. The default spacing is 1/8 inch between lines.
If a [LF] is used to specify the line spacing, it overrides the default table and sets spacing
to 1/8 inch or eight lines per inch. If [ESC] J <n> is used, <n> specifies the spacing in
n/216.
