Most font commands have two versions, one for the primary font
and another for the secondary font. Once selected, it is possible
to switch between them using the single-byte control codes Shift
In (SI) (hexadecimal 0F, decimal 15) and Shift Out (SO)
(hexadecimal 0E, decimal 14).
The primary font is the default font.
A font is a set of printable characters that have common features:
Orientation
•
Symbol set
•
Font source
•
Spacing.
•
Pitch
•
Height
•
Style
•
Stroke weight
•
Typeface.
•
The orientation of a font defines whether the font characters are
printed parallel to the short edge of the paper (portrait
orientation) or the long edge (landscape orientation).
Note: The Printer Status Sheet identifies the fonts by their
orientation. Choosing a portrait font automatically causes the
printer to print in portrait orientation; landscape fonts function
likewise.
Text orientations cannot be mixed in the LJ series 2D emulation.
Therefore once the orientation is selected, only fonts of that
orientation may be printed on a single page.
right margins apply to different edges of the paper depending on
whether portrait or landscape orientation is selected.
Selecting the orientation of a font also affects the coordinate
system used to describe a particular point on the page, as shown
in figures 3-1 and 3-2.
