HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part I

2-2 The Page EN
Logical Page
The PCL logical page (also referred to as the PCL addressable area)
defines the area in which the PCL cursor can be positioned. Although
the printer does not actually have a cursor (like the blinking underline
character used on most computer terminals), the cursor position
refers to the Currently Active Position of the cursor (also referred to as
the CAP). The location of the “cursor” is the position on the logical
page where the next character will be positioned. The cursor can be
moved to different points on the logical page using the cursor
positioning commands (see Chapter 6, Cursor Positioning). The PCL
cursor cannot be moved outside of the logical page bounds.
The size of the logical page for the media (paper, transparencies,
labels, etc.) is defined in Table 2-1 and Table 2-2.
