Ricoh SP 4510dn User Manual

• Setting the orientations of the +I and +B axes also implicitly sets their origins as one of the four
corners of the logical page or overlay.
• For details about the "IPDS Initialization Defaults", see page 39 "IPDS Initialization Defaults".
Other Text Positioning Terms
Some other terms that relate to text positioning and fonts include:
Text Orientation
The combination of the inline sequence direction (the direction which characters are added to a line)
and the baseline sequence direction (the direction which lines are added to a page or overlay) identify
the text orientation for a page. The inline sequence direction can be 0, 90, 180 or 270 degrees. The
machine supports baseline sequence directions that are always rotated plus or minus 90 degrees from
the inline sequence direction. Therefore, there are eight text orientations for printing pages or overlays.
Printing Baseline
An imaginary line that extends across the page or overlay in the positive inline sequence direction (+I),
between pixels, and beginning from the baseline sequence printing coordinate (Bc). (Sometimes shown
as baseline as in the font terms baseline offset and baseline extent.)
In languages with a right to left or left to right reading order (for example, English), the printing baseline
is the imaginary line on which the main body of the character appears to rest. Descenders (the "tails" of
lower case g, j, p, q, and y characters) usually extend below the printing baseline.
In languages with a top to bottom reading order (for example, Kanji), the printing baseline is an
imaginary vertical line that passes through the center of the character.
Each font index record contains a Font Inline Sequence field. The field value specifies a relationship
between the inline sequence direction and the font rotation (the character pattern rotation for the font).
The printer uses the font index record to identify how to place characters on the printing baseline for a
page or overlay. The characters are placed in the combination of the inline sequence direction (the
printing direction) and the font rotation.
The Baseline Offset value is another field in the font index record. This value locates the printing baseline
relationship to a specified character box reference edge.
