Pitch, Point, Positive angle of rotation | HP 5961-0509 manual

Pitch

Pitch describes the number of characters printed in a horizontal inch. Pitch only applies to fixed-spaced fonts since the number of characters per inch varies for proportionally-spaced fonts.

PJL

PJL (Printer Job Language) commands provide job-level control, such as the ability to switch printer languages (or “personalities” - such as PCL to PostScript) between jobs. PJL also provides two-way communications with the printer. PJL can also be used to change the printer’s control panel settings and modify the message displayed on the control panel.

Point

A PCL point is a unit of measurement that equals 1/72nd inch. Font height is measured in points.

Positive angle of rotation

An angle used to create a plot in HP-GL/2 which is rotated in the direction from the +X-axis to the +Y-axis. Note that the relationship of the +X-axis to the +Y-axis can change as a result of scaling point or scaling factor changes, thus changing the direction of a positive angle of rotation. See “Drawing Arcs” in Chapter 20 for more information.

Primary (Secondary) Font

A PCL convention whereby two fonts can be defined internally simultaneously. The primary font is accessed via the control code “SI” and the secondary font is accessed via the control code “SO.” The factory default state is primary font designated.

Printable Area

The printable area is the area of the physical page in which the printer is able to place a dot. The physical page refers to the size of the media installed in the printer.

The relationship between physical page, logical page, and printable area is defined in Figures 2-2 and 2-3.
