EN Text Area 5-11
Text Area
Text printing may be restricted to a specific area within the logical
page using the Left Margin, Right Margin, Top Margin, Text Length,
and Perforation Skip Mode commands. This area is known as the
text area.
The left margin defines the distance between the left edge of the
logical page and the left edge of the text area. The right margin
defines the distance between the left edge of the logical page and the
right edge of the text area. The width of the text area is the distance
between the left and right margins. The top margin defines the
distance between the top of the logical page and the top of the text
area. The text length defines the length of the text area which in effect
defines the bottom margin. The perforation region is the distance from
the bottom of the text area to the top of the text area (top margin) on
the next page. The text area is shown in Figure 5-4.
In general, characters are printed when they fall within the text area.
However, characters can be printed between the bottom of the text
area and the top of the text area on the next page only if perforation
skip is disabled. Characters are printed outside the text area if a
cursor move escape sequence positions the cursor outside the text
area (but within the printable area). Characters that fall on (or outside)
a margin as a result of printing a character string, are clipped
(not printed).
Notes Attempting to print characters across a margin results in the
characters being discarded.
The default text area and the default HP-GL/2 picture frame are
the same.
