T. Margin
Sets the distance from the top of the page to the baseline of the
first printable line. The distance is measured in inches. The
smaller the value, the closer the printable line is to the top.
Text
Sets the page length in lines. For this option, a line is assumed to
be 1 pica (1/6 inch). If you change the Orientation, Page Size, or
T. Margin settings, the page length setting automatically returns
to the default for each paper size.

graphics character table or the italics table. The graphics table
contains graphic characters for printing lines, corners, shaded
areas, international characters, Greek characters, and
mathematical symbols. If you select Italic, the upper half of the
character table is defined as italic characters.
Country
Use this option to select one of the fifteen international symbol
sets. See "International character sets" on page 413 for samples of
the characters in each country's symbol set.
