Pen

Although this printer is a laser printer the HP-GL/2 and HP-GL graphics languages 
retains the notion of a pen and allows you to select between two pens,  white and 
black.  You must select a pen before you can draw anything.  The HP-GL and HP-
GL/2 language were originally developed for use with plotters and the terminology 
remains. 

Perforation skip

A feature whereby the printer automatically compensates for a page break and 
resumes printing from the top of the text area on the next page. 

Permanent font

A downloaded font that is retained when a printer reset is performed. 

Permanent macro

A macro stored in the printer that will not be erased if the printer is reset. 

Physical page

The paper or envelope on which the printer prints. 

Picture frame

The area of the physical page in which HP-GL and HP-GL/2 graphic images can 
be printed. 

Pitch

The number of characters in one inch of text.  Only applicable to monospaced 
(fixed pitch fonts.) 

Plot

A drawing produced using the HP-GL and HP-GL/2 graphics language.  So called 
because the language was originally invented for use with plotters. 

Plotter units

See graphics units. 

Point

The standard unit of measurement for character height.  Equal to 1/72". 

Point factor scaling 

A form of image scaling using the SC command in HP-GL or HP-GL/2 mode in 
which the user units and the location of the scaling point P1 are specified in terms 
of graphics units. 

Point size

See height. 

Polygon 

A shape consisting of one or more closed groups of connected lines. 

 
Polygon buffer

An area of printer memory in which you can store one or more polygons and sub-
polygons defined using HP-GL and HP-GL/2 commands.  Some HP-GL and HP-
GL/2 commands use the polygon buffer automatically. 

 
Portrait

The orientation in which the side edges of the page are longer than the top edge. 

Posture

A component of a font's style - whether it is upright or italic. 

Primary font

In LaserJet mode the printer maintains two current font settings.  The primary font 
is the first of these. 

Print model

A way of describing the interaction between different graphic elements ( source 
image,  pattern and destination image ). 

Printable area

The area of the page on which the printer can print.
